One time after synching my iPod all the apps I've purhased crash immediately upon launch. The onlyy ones that work are those that came pre-installed on the iPod. Also, some of m music will not play! I press the play button but nothing happens and none of my videos will play. I have tried EVERYTHING! Restarting, rebooting, restoring, deleting all my apps and reinstalling, downloading a free app- EVERYTHING. Someone please help, I've tried all these solutions more than once. If you don't know how to fix it, can you tell me if they'll fix it if I take it to the apple store?
