Guild Wars 2

Hello, ive played and enjoyed your game enough to be very frusturated when I cant! I started playing with getting some errors talking about a missing file (572) then it got more and more intense, and now I can only login to my hero selection screen, but when I press play I get this error everytime.

My pc should be top notch
running the GeForce GTX 680
with Intel Core i7-3770k CPU @ 3.50Ghz 400.GHz
and 16.0 GB RAM!

Ive tried to reinstall, ive tried to create a new hero, ive tried to repair!

I have all my settings on max

I need some serious help! I get this error EVERYTIME i select my character and press play! I get to see some of the loading, but before i get to even see my character I get this error!
