I've just downloaded the ad-supported version of FC. It installs fine, and the 'configure FC' loads when I first boot up, but when I go to open the game I get a blank screen, and have to close the game through the Task Manager. The Sandbox works fine. I think I've got everything up to date, and I've tried reinstalling a couple of times. What am I doing wrong?

OK, so I read in another thread here to just leave it on the blank screen and see what happened. After about 5 minutes the main menu loaded. After I hit new game the loading screen comes up and that takes about 10 minutes before the game loads. Any reason why it would be taking so long to load only to work fine once I'm in the game?
