Could Not open main init file: driver

[themanticore]

I got this same error when I tried. Apparently it was a problem with Steam. Go to the game in your library, right click it and go to Properties. From there, (and I forget which tab it's under) you have to verify the game's data cache. It should reacquire the file you need and work.

I updated all my drivers and i still get this message everytime i launch it. Nothing pops up except this message. Tell me if you need hpl or whatever.
