Forum:Borderlands freezes when starting singleplayer

Sorry, this is my first post and i don't really know what I'm doing. I downloaded Borderlands roughly a week ago, it was working fine but i couldn't die. I found out about god mode and how to turn it off which i did but now when i try to use the game it freezes on the loading screen where it gives you tips. I can load the game properly and the menus are fine, but when i click on my character it freezes. I know the game is working underneath because when i press the mouse i hear it fire. I have to work my way through the start menu by sound to get out of this. Whats wrong?
