I'm glad that you got it resolved. I still can't seem my purchased apps in the purchased tab. I can do everything else in the app store so it's not a big deal, but it's weird and ... annoying as well.
The odd thing is that the app icons are there on the screen because I can tap on the blank screen and that will take me to the app description page for that app. But the icon is invisible even though the link to app is on the screen.
So I have no idea which app I and tapping on! đ
This is one of the oddest things I have ever experienced on my iPad(s).
