Game drops to Taskbar
 

So i went to log in tonight and i run the exe the window pops up for the patch or paly options when i click play the EQ icon comes up the game window pops up for a second then drops to taskbar. When you scroll over the window it's just a black screen and when you click it the window won't pop up.

Any idea how to fix this?

So when i right click the window and go to eqgame the window pops up and it says Error in XML
Error in your GUI XML Files: Check UIerrors.txt

When i go in to the UIerrors.txt there is nothing there besides it saying it created the log tonight when i tried to log in.
