A couple of months ago my windows screwed up which resulting in me reinstalling it. I didn't want to reinstall all my programs so I copied the program folders back across. I eventually removed GW to save space, but recently I have tried to reinstall but with no results. all other online games work without any issues, only GW seems to have an issue when I try to install. I have already tried compatibility mode, running as administrator, installing from discs, installing from the downloadable client, turning off my firewall and antivirus, and forwarding ports 80 and 6112.
