I have a similar problem, when I open the Mac GW2 client and login, I press start but then the screen goes all black. It stays like that for 10 seconds then I return to desktop. I have tried FlamingFoxx.1305 solution and at the first time it worked and I was very happy, but then I it did not work anymore. I tried 10 more times to remove the folder but without success. Everytime I delete the folder and then open the client, an fast update occurs and the client does not remember my account details. Can someone help me please?
