You have to configure your router, modem/router, firewall and antivirus program for GSA and for your games. I've been told that GSA doesn't work with FireFox. I hear that it will work with Win 7. I know with Vista with sp 1 and sp2, you have to click thru several errors to get into GSA. I don't know if that happens with win 7 also. Hope this helps and thanks for posting.

Hi
Welcome to the Forum

Please make sure that Aphex.exe is allowed into your modem/router, router, firewalls, both enabled and disabled ones and into your antivirus program. Please try installing GSA with your Firewall and antivirus program disabled until you can successfully get into GSA. If it's stalling at the pressance part either something is blocking the program or the program itself was having a problem at that time. I hope this help and thanks for posting.

yeah windows 7 isn't fully supported even now, i fixed it by changing the program compatibility to XP SP3, now it works fine, hope this helps, and i hope gamespy pulls there act together to fix gamespy for windows 7 and get there master server to accepts new server which still doesn't work properly, like it did mid last year

Good Luck.
Miss playing you.
