Can´t Connect To Online Servers PLEASE HELP!

[CodeBr3ker]

Hey people.

Suddenly I can´t connect to the MW3 online server. Whenever I enter a match and the map has loaded, it throws me out and gives me this messege: ERROR: "Files different from the server"

I don´t understand this at all, because I just played one match, and when I tried to enter another, it have me this messege. Any ideas? Fresh install?

Thanks #BroLove
(Note: I didn´t use aimbot or a such thing. I used MultiTrainer by CellProduction to edit Prestige tokens, Cheat Engine for rank, multiunlocker for perks and weapon level and I made my classes colored with the ^ sign.)

Verify your files with Steam.

Usually happens when you enter a hacked lobby that changes your Cvars and edits your fastfiles ( in memory )
