Weird updating problem

[hawk1226]

So since i haven't been getting notified of app updates through the app store (I know there is an update available for enigmo) i figured i'd try through itunes. When i clicked check for update, it said there was one update. When i click the type "1 update available" it brings me to a page in itunes that says "******* (My friends name and then his email) has no current updates available to check for updates on another account, sign in with that account"

but in the top right corner it shows i'm signed in with my account...

I have the same problem! (Along with another problem when updating apps directly on the iPhone). I made a post about it last week (here) but no-one replied. I hope someone has the answer... or any ideas...
