I just downloaded the Cheverolet Impala Cop Car Addon, and I used everything possible to get it worknig on MM2, but nothing does.
It doesn't show up in the cars list. And i put the cop car and addon_vehicle.ar thing in the MM23 folder

What the hell is going on? Whenever i download a car from MM2X, and try to open it, it says that the file is corrupted!!! Does anyone have any ideas on what is happening???!!

Thanks

Download WinRar, i thinks it winrar.com
After you download it, open it with it and there you go.
