Have you got any music at all loaded on the iPad?
If not:
Most of the tabs at the bottom are for organizing your music, and I wonder if the lack of any songs could be causing problems. If you have any music from the iTunes store, try going to the purchased tab in the store and downloading one or two songs, and see if that helps.
Since it seems to be a problem with the app (since even the More tab is missing), you should also try the usual fixes, if you haven't already done so. I'll paste them at the bottom of the screen.
And while I"m at it, here are the three (as far as I know) requirements for Home sharing to work.
- It must be enabled in iTunes Preferences on the computer.
- iTunes must be running on the computer.
- You must enter your AppleID and password on the iPad in Settings > Music.
Good luck.
When you have problems with an app it's a good idea to clear it from RAM.
Close/Clear the app: With the problem app closed, double tap on the Home button to get the multitask bar. Tap and hold on any icon in the bar until they jiggle, then tap the minus sign on the problem app. This will remove it from RAM and insure a clean start the next time you launch the app.
If that does not work try a restart,
Restart: Hold down the power button until the power off slider appears. Slide it off. When the iPad finishes shutting down, hold down the power button again until the Apple logo appears.
and then a reset if that does not work.
Reset: Hold down the power and home buttons until the Apple logo appears. The iPad will reboot. This usually takes a bit longer than a restart.
