When I click on the game icon, the game starts to load as if it is updateing the game. When it gets to 100% a pop up box titled "Gw.exe" appears telling me that "A serious error has occured that prevents the program from continuing to run." It then prompts me to send a report to Arena Net. This game has always run perfectly on this computer before, is there something wrong with the game right now? If not, what steps can I take to resolve this problem?
