Place your mods in the "mods\" directory in seperate directories.
So if you have a mod called "Best Mod Ever", you go into the "mods\" directory and make a directory called "Best Mod Ever\"
In there you place the files. Usually this is a directory called "maps\" with "mp\" in it.
Do not try to place the single *.gsc files directly inside your "Best Mod Ever\". It will not work.
If you own a packed mod (*.ff format), place them inside the "mods\" directory (not within ANY other directory).
Q: When I close the game, I get a WIN_ERROR.
A: /care, click OK and close it. Sometimes taskmanager is necessary to fully kill the process. Has no priority at all.
Q: When I run *******loader.exe and Black Ops crashed before ("Do you want to reset your config?" question) and I click away the popup to fast I get a Fatal Error.
A: You started the game before the dll got fully loaded and therefore it crashes. Wait until the loader is closed and then click Yes/No/Cancel (I recommend No).
