It means you have VAC and you can't play cuz they fixed it.
The only solution for this problem is just to buy a new copy of MW2
Hi guys.
Yesterday I got a problem in the MW2: After pressing the "start" I get the message "Error connecting to the Steam".
A Steam restarting or reboot my PC not not solved the problem.
Pls help (sry for my bad english)
