O FIX YOUR MINI MAP OR ANY EFFECT AND I MEAN ANY ON YOUR GAME FROM MOD SERVERS, THIS IS WHAT YOU DO:
[ MAKE SURE YOU ARE SIGNED OUT OF STEAM and ANY GAMES ONCE YOU DELETE THE FINAL CONFIG FILE ]

1. Go to my computer
2. If you running both 32 bit and 64 bit then go to your 32 bit folder (x86) or what ever folder you have "steam" in.
3. Enter steam folder, then scroll down and enter "Steam apps".
4. Then you should see a "Common" folder, enter it.
5. Then their should be a folder saying "Call of duty modern warfare 2", when you find it, enter it.
6. Then you should see a list of about six folder, find the "PLAYERS" folder then enter it.
7. Finally when in the players folder, find any files that say "Config_mp" CFG file or "Config file", if there are TWO files that have config in their name and ONLY CONFIG, then delete them both ( remember you must be signed out of steam and any games once you delete this file, and delete it entirely from your recycle bin).

!* The only thing you will have to re configure after this process if you normal game setting such as mouse sensitivity, your advanced graphics setting for in game (spec map) *! THIS IN NO WAY RESETS YOUR RANK OR AFFECTS ANYTHING ELSE!!.
