All I Get Is A Black Screen

As I stated in the title when I try to start the game, the screen goes black and I have to Ctrl+Alt+Del to get back to the desktop.  The wierd part is that the game worked fine on this computer a few weeks ago (the last time I tried to play), and as far as I know nothing on my computer has changed since then.  The debug file says what the error is, I just don't know how to fix it, so any help will be greatly appreciated.

Here is the debug file:
