I was experiencing the same problem and tried all sorts of stuff, including items in this thread with no luck, this is what ultimately worked for me.


Download iFunBox (or other utility that gives you access to the filesystem)
Delete the _iTunes_Control folder
Delete everything in the Purchases folder
Force a sync in itunes
Force delete itunes, then re-download using your same apple id
Profit.


So far I haven't seen any weird problems, other than my songs now sync.
