Okay, so every time i try to log into MW2 it gives me i have entered a incorrect username. But i am absolutely positive i am putting the correct username in. Any suggestions? :?

Either delete IW4M.ini or make a new text document, name it IW4M.ini and then what you put inside it:

forumusername
forumpassword

Thanks for the quick reply. But I got it fix. I was able to join a zombie match but now when I try to join another match it shows me this>

 

 

Just posting in case I get a quicker response

Might be a problem with the zombie mod, can you join other servers?
