How can you tell if the full game has even downloaded?

All I get is a temporary black screen then it jumps back to my "desk"top view.

I also have over 1gb of space on the Ipad2 but the game won't start.

Similar problem here.

I bought it for my iPad and download the software.

When I launch the program the screen goes black, then the program sits open as a blank screen in the background and won't actually open the software.

Tried to delete and reload the App. No changes.
