Call of Duty: Modern Warfare 2 Multiplayer error

Well, i only get one error, but i can't fix it.
It says: No IWD files found in /main in the IW4 Console.
I think it could be that something is missing in "C:\Program Files\Activision\Modern Warfare 2",
Because i didn't have anything in there from before, so i made the folders myself.
Then i added the files from the "# Crack/Server" in there.


Please help me :] That would be nice if i could play Mw2 multiplayer steam for free.
Thanks..


//EDIT

Here is full error:

----- FS_Startup -----


Error during initialization:
No IWD files found in /main

Hello,

Please note that our Modern Warfare 2 Multiplayer IS NOT WORKING any more. (See: https://games4theworld.forumotion.com/t4-modern-warfare-2-multiplayer-crack-answered )
This error is caused because of that crack. Please uninstall the crack or reinstall the game to fix the error.
