I've had this problem a few times lately. First off, I'm not a blabbering 13 year old with a new piece of technology; I know what I am doing. However, since taking up actually buying some of the better Apps off the Appstore now, I'm slightly concerned. Some of the Apps I've bought don't seem to want to sync over. I recently bought Retro Defense, and I'm quite upset that I am unable to sync it. Furthermore, since I tried syncing Retro Defense, it seems that my free app Facebook has been removed (from my iPod Touch) also. I'm not a huge fan of performing a restore, and would highly prefer not too. Any insight, or suggestions in solving this problem would be greatly appreciated.
