I was in GvG yesterday when all of a sudden the game decides to freeze up, but thats common; but this certain freeze wasnt common, I sat in my chair for 5 minutes before i minimied the screen to see if I dced. Of course I didnt dc, and the game just suddenly closed itself. I got an error message, it had no code and it didnt say what the problem was, it just said to report this problem to ANet (and I did). Was I getting hacked?

Any thoughts on this are highly appreciated.
Thanks
