I loved the demo and went to buy the full version. The market took my $2.48 (?210), but will not download the full game. It says Purchased, but when I click to download, it says "Authorizing...," "Your Download will begin soon" then shows the download icon on the top for a brief second before disappearing. No download or anything. How can I get this game? I see other comments in the marketplace that others are having a similar problem. It only seems to happen with this game.
