cd key authentication invalid for internet servers Counter Strike Non-Steam ( Nosteam, warzone,)

In this Video I show how to fix the error, it took me some time to find a fix, so I made this video. I am using nosteam version but I got the same error on the warzone version as well. sorry for the poor sound .....cold # # # if you are having problems with the rar ; download this and just change the file extension to dll. hope this works !
