Download/Update buttons non functional after iOS 6 update

Updated iPad 2 to iOS 6 tonight, initially I had the problem when app updates don't start and just hung. Restarted iPad and the updates appeared to have stopped. Went to update all apps again and the button did nothing. This is the same with all new app downloads/iTunes song purchases/individual app updates. The button does change from the price to "get single" or whatever, but the button just does absolutely nothing when clicked upon.

All occurring over wifi, I don't currently have the laptop the iPad is synced with me but will tomorrow.

Can anyone help me with this very frustrating problem?

I have tried restarting iPad, restarting all apps, signing in and out with my apple ID, nothing appears to work. I can't see any downloads hanging in iTunes.
