I've been having the same problem tonight. I've been playing the last several days with no issues at all, now I can't play a single battle without the game freezing up the entire computer forcing a restart. I don't even have to be in a battle for it to freeze up. Once it happened within seconds of logging in, before the game fully loaded, have also had it happen when looking at recent news and just on the main Port screen. This is incredibly frustrating when all I wanna do is relax by launching torpedos at my enemies. P.S. Running WGCheck didn't find any issues. P.P.S. Running the game as Administrator seems to have helped, haven't had a crash since trying it.
