I am having the same sort of problem. I tried to order the game after the demo, on the Reminder Page. However it kept telling me "your basket is empty". So I gave up on that and ordered it directly from the web site. All went well with the download, but it did ask me to uninstall the previous version before continuing, which I did. After replaying the opening sequence, the game asks me for a "Registration Name" (I'm assuming that's just my name) and a "Key". I had received a confirmation e mail with my order number, but no mention of a KEY. My game never tried to automatically retrieve a Key. It expected me to have the info. I've e mailed everybody; Troy, support and Digital River. Would love to play the game. I've been following it for some time. Hope help arrives soon.
