Impure client detected Invalid .IWD files referenced!

Please help

Read instructions on the Compiled Files tutorial.

 

In your MW2 folder (where the iw4m.exe is), create a new folder called raw. Then put your raw_65.iwd there. Extract it in that folder using 7-Zip, so you have all the files in there. So it should be mw2/raw and all the folders in raw.

 

 

 

 

Notice the directory as well.
