Return To Castle Wolfenstsein Ver1.0

[Josey Wales]

Hi all.
I have the above game working fine but after adding the +set sv_cheats 1 to the shortcut target line on my desktop the cheats dropbox tells me that "the cheats aren't available on this server"
I am not trying to play on a server.I am playing single player mode and the shortcut target line has the wolfsp.exe not wolfmp.exe, I have placed the user.cfg file in the "main" folder and tried saving and loading a game but still the same message when I type a cheat in...
Please help me! Confessed Cheater! :'(
