Welcome to the forum ;D Mangley was nice enough to give us his config file for Hammer, so all you have to do is put your steam login in place of USERNAME, you can get the file here (http://forums.goldeneyesource.net/index.php?action=dlattach;topic=2954.0;attach=853), once you have edited it, place the file in Steam\steamapps\USERNAME\sourcesdk\bin\source2007\bin
you will also have to add (x86) at the end of program files if you're running on a 64-bit OS. If you have any questions about running the servers, feel free to snipe me a PM.
