Guild Wars 2

hey guys, i just got this problem right now, about 5 hour ago i still playing GW 2, but i got sleep then after i wake up and want to play again, theres an update, and when i update my game client, this happend, i dont really know what to do, i try search for every solution but i dont get it, if anyone knows please share here, thankyou!

im using amd fx-6300, and amd radeon HD 7800

Similar problem, “unable to verify the Guild Wars 2 executable” reinstalled the client but nothing changed. I guess I’ll reinstall the whole thing now? yay?

Nope. Shouldn’t have done that.
Not sure how i didn’t see the other thread.

i also try GW2 repair, and it still doesn’t work
