In fact, it's quite simple: I can't play GW anymore.
After having some serious internet problems (Connection failure etc.) we called a guy, and he fixed our internet

When I opened GW, I got the screen that GW was connecting to A-Net, and that I needed to download a file (automatic updates). But then, IT WAS ONLY 1 FILE!. I tought, ok, I'm playing GW in a few seconds. Not! Somehow he just didn't wanted to download the file, and now I can't play GW anymore...
Anyone got any solutions?
