[SOLVED]Mw2 liberation didnt unlock console

Hi, I am banned on my 1st acc and Iam using it for hosting mods on lobby tracker. Ofcourse I need to have mw2 liberation to run the game, but the problem is, that it didnt open the console (I had ticked the appropriate option). I can host without it but its very useful.
Does anyone know how to fix it?

Have you pressed F2 to unlock it ingame?
*Can't answer more if you reply, goin to bed*

Ofcourse I had.
