Hey. I recently got steam and then downloaded alien swarm. I also joined the videosift community. Aside from that I'm having trouble getting the game to start.

Upon launch I get a black screen but I can hear sound. When I move my mouse around I can hear the mouse rolling over menu options.

So I put the following launch options in:

-width 1280 -height 1024 -freq 60

Which is what I'm using. But to no avail. Anyone have any ideas?

I've got a:
Windows XP
RADEON 9200


Given that I can hear sound, but can't see crap I'm left wondering WTF. I also put the game into -windowed mode, and that gave me the same behavior except in a window.
