Ever since I bought this game years ago, it has always gone to a black screen on launch, then going onto the character selection screen. However, I tried logging in just now as usual, only to get stuck at aforementioned black screen. Trying to alt tab would not work, and had to open the task manager to kill the process. Guild Wars 2 was showing very little activity and was “responding”, but while it was active it would not let me click anywhere and had to use the keyboard to stop it.
Edit: Game has given me no problems after I restarted the application.
