Alright so I downloaded EQ2 and proceeded to install and update it. After the 6 hours or whatever I launched the game. When I did the screen went black like normal and the ingame mouse cursor came up. But a few seconds later a square of the screen in the top left corner about half the length and width of the screen went to the desktop. The rest of the screen was still black. I redownloaded and reinstalled the game two more times but it does the same thing. Can anyone help? 

PS. Vanguard runs fine

I honestly have no idea. I've never heard of that before. Post this on the official forums.
