Guild Wars 2

So just yesterday I was playing and my game started to lag and the screen went black. I have reinstalled it 3 times and now i cant even load into the world without it freezing and crashing. This picture is the only thing that comes up when it crashes. Is anyone else having or has had this problem?

Have you tried deleting the Guild Wars 2 folder in your user Application Support folder in your user library? – The instructions are listed in a lot of threads of this forum.
Also try repairing your disk permissions and make sure your computer has plenty of free space left on the hard drive.

yeah I have. This seems to be a separate error
