I tried starting up the game just now and everything's whited out. At the sign-in screen the background is all white, but I can see the buttons just fine. At the character select, again I can see the buttons fine, but none of the graphics. And, while the load screen is perfectly fine, the game world as the same problem. I can see the enemy names, and I can see the edge of my character, or something, if it obstructs a name, but other than that it's just blank white.
What's going on!?
