My brother plays at COD with fourdeltaone. So I decide to play too. But unfortunately every time I'm on the installation procedure it does not ask me to register me and I'm connected directly to the account of my brother. A problem of IP something like that ... What to do? How?

 

Thanks you.

Delete iw4m.ini in your MW2 folder.

Now my game is not cracked and the crack does not work anymore.

It's my fault. It works. Thanks.
