MW2 Liberation

when i used Mw2 Liberation it told me to let connection acess so i restarted it and now when i press load game it ask says preparing to launch mw2 but then nothing happens. Anyone know whats wrong?

Try Downloading a New version.

Make sure you run Steam AND Liberation as administrator. Also, make sure you don't have more than 1 copy open. Sometimes they are hidden so you have to press Alt+Tab and close the extra ones. Also, have you ever played the game before? I met someone who never played multiplayer before and just ran Liberation first.

Also, make sure you have Visual C++ 2008 Installed:
32-bit: Download details: Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)
64-bit: Download details: Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)

And also, a minumum of .NET Framework 2.0:
32-bit: Download details: Microsoft .NET Framework Version 2.0 Redistributable Package (x86)
64-bit: Download details: Microsoft .NET Framework Version 2.0 Redistributable Package (x64)

Go to Start > All Programs > Accessories > System Tools > System Information
Look at System Type. x86 = 32-bit and x64 = 64-bit!
