I think that sv_master! should be set to sv_master1
I noticed that when i copied the config file, changed it to sv_master1, and my server worked.
There is no problem with the raven master server, its the gamespy one provided earlier.
master0.gamespy.com:27900 is the STV Elite Force gamespy master! Hehehehehe
Someone asked earlier what rconpassword is.
Rcon is a tool you can use to administrate a server when its not running on your PC. When you are connected to your server, you can do this:
Press Shift + `(underneath Escape)
Then type this:
/rcon WHATEVER-YOU-SET-RCON-PASSWORD-TO-ON-THE-SERVER map ctf_bespin
If you typed the pass right, this should change the map to ctf_bespin.
