I'm just coming back to the game after 1+ year being away.
I installed updates, entered my account details, but when I press the PLAY button on the client, the game doesn't load. The GW2 game icon opens in my Windows bar, and then closes after 2 seconds.
I've even just tried reinstalling the whole game from scratch, with the same results. I've just updated my card video drivers too in case it was that, but nothing.
Anyone else experienced this? I'm all out of ideas...
