Issues with iTunes and restoring iPad from back up

[SaberSerene]

As of yesterday my iPad was on iOS 7 beta 6, I decided to downgrade to iOS 6. (I did update iTunes to latest) That worked, but again changed my mind. I restored with the iOS 7 GM. I was notified via a pop up window to update iTunes. I had to download the unreleased version of Itunes. I chose to download beta 2. Now the iPad doesn't sync.

If I didn't run into this issue I was going to restore from back up. The back up I had when my iPad was on beta 6.

Help!

Did you get the version of iTunes from your developer portal?
