Guild Wars 2

So, since this new updated launched I am unable to do anything. It simply leaves me with an error message. The first time I started the game it seemed to work fine, once I hit play the game started but I got to a BSOD instead of a character selection screen, after that the only thing I got is the message shown in the screenshot.

The question is; do I just sit and wait or is there a solution?

Have you launched the game with the -repair option?

No, is that where magic happens?

I actually just did some searches for solutions and came across;

And:

i have found a way, how it is running. right-click at the .exe , compatibility problems.
then select windows xp service pack 2 and start.

So I went on and tried that out and it actually worked.
