iTunes 10.5 Hidden music

[clickart]

I tried searching on the forums but cant find anything. This seems like the appropriate place to post, hopefully. My iPhone 4 is updated with iOS 5 and I have iTunes 10.5 beta installed and every time i click music, it shows up but then disappears and goes to some ping ******** page.. Even when I click on purchased items, it shows my songs for a split second then disappears and goes into the ping page.. Is this a common bug?

I am on windows 7 32 bit.

Thank you
