• Confirm that your device has (unlimited) access to the internet. The jivelite Applet Installer (Settings > Advanced > Applet Installer) gets the list of available applets from your (local) LMS server. Your device will then (try to) download the applet directly from the source (URL).
  

• Doesn't happen very often but still: the server hosting the applet files (http://af1.jerq.org/) could be down. Just try again later.
  

• piCorePlayer: If you're running piCorePlayer 10+, go to the Tweaks page (web UI), scroll down to jivelite and make sure that you are using the original jivelite and not jivelite-vis. This applet does not work with jivelite-vis.
  

• piCorePlayer: You have downloaded and installed the DFS skin installer applet package. But then instead of using the Quit menu item which only restarts jivelite, you rebooted piCorePlayer (not necessary). If you did so without backing up changes to the SD card, the skin installer applet package did not survive the pCP reboot (because it was not saved).
  In short: Just use the Quit memu item to restart jivelite. Do not reboot pCP at this point.

• Go to Settings -> Advanced -> Applet Installer and confirm that Recommended Applets Only is disabled.
  

• Confirm that your server and device both have internet access.
  

• If it's a caching problem, try this:
  

  • reload the LMS Settings -> Manage Plugins page so the server has the latest list of available applets
    

  • if you enter the Settings -> Advanced -> Applet Installer menu and it doesn't show the latest update, exit the menu and wait a couple of minutes before calling it again.

This is a jivelite quirk that's not tied to any skin in particular. Just enter the NowPlaying screen using the top right note icon. Then go back and try again. That usually solves it. If not, make sure that you have selected a player and that this player is connected.

You need to click/touch the track title in the title bar. The lyrics (text) cannot be used for that because you can scroll up or down in the song lyrics using click-hold/touch-hold.

Sometimes you need to switch to another Now Playing view before the changes take effect.

To rate a track directly on the Now Playing screen, the track must be part of the LMS library (applies to local and remote/online tracks). And you need the Ratings Light plugin. Make sure the Now Playing screen setting Rate tracks directly on screen is enabled.

To unrate a track click/touch the space to the left or right of the rating stars. Since the space to the left of the rating stars is quite small on Now Playing views with artwork, it's probably better to click/touch the space to the right (about 40px wide).

Alternatively or additionally, you can replace the Shuffle and Repeat buttons on Now Playing views that display track ratings with rating buttons that will increase or decrease the track rating by half a star. This setting is not enabled by default and can be change here: Settings > Screen > Dark Flat Skin.

On SB Touch devices you can use your remote keys to rate tracks (Ratings Light plugin required). The assignment of the SB Touch remote control buttons is explained in a FAQ further below.

Please note: on piCorePlayer, the VU meter you select for the Dark Flat Skin is also used by the Dark Flat Grid Skin. You can't set a different VU meter for the Grid skin.

For guaranteed success:

• SqueezePlay: restart SqueezePlay.
  On Windows (and possibly Linux) selecting a different VU meter requires admin privileges. Please read the corresponding FAQ article below
  

• piCorePlayer: use the Quit button to restart jivelite.
  

• SB Touch: reboot your device.
  
  

Works sometimes:

• Go to Settings > Screen > NowPlaying > NowPlaying views.
  

• Deselect the analog VU meter view.

• Exit the menu.

• Then reenter the menu and select the analog VU meter view again.

Rate the track currently playing on your SB Touch by holding down a button on the IR remote.

Press and hold the key until you see the new track rating on your display confirming the new track rating.

Key map:
keys 1 to 5 = 1 to 5 stars
0 = unrate
6 = subtract 1 star from current rating
7 = add 1 star to current rating
8 = subtract 0.5 stars from current rating
9 = add 0.5 stars to current rating

On your SB Touch device:

• Go to Settings > Screen > Select Skin
  

• set the Touch Skin  → Dark Flat Skin

• set the Remote Skin  → Dark Flat Skin Large (Remote Skin)

• set the Enabled skin after reboot  → DFS Touch Skin - or even DFS Remote Skin if you're always using SB Touch from a distance

The VU meter and spectrum visualizer are only displayed if the device running jivelite is also a local player (e.g. if you have SqueezeLite running on your piCorePlayer device).

WINDOWS:
Installing and uninstalling the skin and changing the VU meter design require admin privileges on Windows, i.e. you need to `run SqueezePlay as admin` to install, uninstall or change the VU meter design.

The installer has to rename files in and copy files to the NowPlaying and Clock applet folders in the protected jive applet folder. And on Windows, creating symbolic links (to change the VU meter design) seems to require admin privileges too.

LINUX:
It probably depends on where you've installed SqueezePlay. The installer requires write permissions (755) to rename files in and copy files to the NowPlaying and Clock applet folders in the jive applet folder.
If you install the skin using sudo, it will install the userpath skin files in the root user's home folder. And nobody wants to run SqueezePlay as root all the time.
So either the installer can write to the jive applet folder or you install the applet (files) manually.
