I get a white screen after I selected the servers, apparently the game loads (after an unusual 5-10 minutes, so the first times I thought it crashed) and I can play, but I still consider it odd...

Does anyone know what's causing the white screen? I could load the game properly once, this afternoon, meaning with a loading screen (or at least a picture with ROHAN's featured artist) but the white screen popped up again when I launched the game a few hours later.

I don't get an error message nor does it stop the game, but maybe somebody knows how to fix this?
