Having same issue, it seem like this issue is not uncommon? It's been on going for years, but no solution?Been playing fine without any issue for a couple of years and suddenly, keep having black screen, but music playing on background and mouse cursor moving.Tried all above solutions, none worked.Sent complain to arena net, no reply, no response. Who should we go to? What can we do if no solution /guide being given?We would like to continue playing this game, becuase we like it, and this is ruining our gaming experience... At least an administrator reply to this thread please?
