Please help

It seems that you've been using the alterrev version before. Try using a fresh copy of the game, and then try to install 4D1. You can use the skidrowversion from the pirates on the bay.

Yup, he used aRev.

 

In your MW2 folder, delete iw4m.dll, libnp.dll, raw and iw4m.exe.

Then use the installer:

and select your MW2 directory, click Install and click Play IW4M in your start menu.

Thanks guys it's working
