Yo! I had the same problem as you: I started the game, clicked on download updates, then it told me I had to register the code and when I typed it in and pressed register it didn't work, like if nothing happened at all. So I emailed support and they sent me a web address for Impulse. It allowed me to put in my serial code and get the updates for the game! Here's the web address for Impulse! http://impulsedriven.com/about.asp
