okay, iPod
nano_1GB or silver- (or anyone else)... here's a similar problem:
60 GB iPod Video, software 1.2.1, up-to-date iTunes, just bought Sudoku off of iTunes store. Under Library (left menu) on iTunes "iPod Games" shows up. When I click that, the Sudoku description and instructions come up w/ a drag-and-drop picture of the game. Tried moving it to iPod, but the circle-and-slash icon appears. Under iPod, in the Games tab, Sync Games+All Games are both selected. The first time I tried sync-ing, the "does not have authority to play on this computer" warning appeared. However, I have tried sync-ing again and again, and the warning has not appeared since the first time. Now when I sync, the process seems to work, but the disconnected iPod (under Extras and Games) does not show the name of the game. What do I do? You're the genius!
I also read somewhere in here that I might have to Restore Original Settings? That's not gonna happen. I have too many songs I'm going to lose. If that's really all I can do, I'm going to be verrrry mad. Please don't tell me that.
