when i start the launcher from the startmenu it says:

 

problem loading your configuration files. please resart mw2 again

 

can some1 please help me??

Since when does The Internet need help ?

 

On a side-note: restart MW2 oh and try deleting config_m2.cfg in your /players/ fodler.

That only happens once..

Again, should've gone in IW4M.....

If it happens constantly, delete your options (config_m2) in players folder, as that's probably what's causing the problem (problem loading your configuration files)
