Cod4 Multiplayer won't work!

So recently I decided to use this mod menu for campaign called project poison on cod4 and ever since I used it when I try to play multiplayer my game just black screens and freezes I'm not sure why I've tried waiting a day to see if then it'd work I tried restarting my game nothing has worked! **Update** I now know that cod4 multiplayer is only working on other accounts it no longer works on my main one it just freezes when I try playing it does this mean I got banned?
