wierd black screen in-game

So I recently started playing crossfire again since bf3 doesnt seem to be working. Anyway, I loaded up a game of CF and everything was working perfectly. Running between 30 and 70 FPS, the game was running perfectly. Then a few hours ago, I loaded the game again and the game gives me a black screen when I try to play. The menu's are perfect. When I click "Join game", then the loading screen pops up. When the map is loaded, the game goes into a black screen. Not a normal black screen however. All elements of the user interface are present - the weapon I'm using, the ammo it has, the names of friendly players above their heads, the map - all the user interface is there. However, the raw game and gun model is not there. There's a black screen instead.
