Guild Wars 2

I have seen on here that someone suggests changing dns. I am not real tech savvy so how would i do this. I run windows vista 64 bit os. Any help would be great, would love to play the game since i just bought it 6-16-13.

I have installed and removed and re-installed that game, used all the suggested fixes like turn off fire wall and avg. when i get to login screen it stops on 1 file remaining and 0.00kb to be downloaded. my connection to the internet is working fine, i have done everthing on the forums and still can not play. I live in kentucky that is were i am trying to login from. hope this helps to fix the problem.
