syncing ipad

[ron.new]

I use a windows 7 computer to sync the ipad. I downloaded itunes 10.4.1 and the next time I synced, it wanted to erase all my music, movies and apps. I discovered that for some strange reason, my itunes music file had been moved from the music library to my pictures library. I had itunes find that file and all my music and movies were there, but itunes still wants to erase all my apps. How can I prevent that from happening.
Help, please.

Did you previously have this iPad synced with a different computer?
