(adsbygoogle = window.adsbygoogle || []).push({}); Ok, so I downloaded the Skidrow version of MW2 for PC. I was able to install Steam and I am able to access multiplayer by using the Zero Gear Demo to run MW2 Multiplayer. However, when trying to use MW2 Liberation, when I click on the .exe it tells me I need to Install MW2 first even though I already have it installed. Help would be greatly appreciated. Thank you.
