Hi
are you sure that you already installed the clientmod V13 or the MarkyBoy Mod V11 ?
In such a cases , go directly to your swatdedicatedserver.ini file and search the line ( Ctrl+F ) adminpassword
it shoud be something like : adminpassword=ukgamers
Be sure that you don't make any settings meanwhile your server is runing , otherwise it won't works
But i have another question for Chris

I saw new mods

( which is huge ) but i want to know how it works , new maps and where all my clan can download those maps in swat4 ??
blkwtchlostsoul if you have any other questions i can help
