Ok, so i got this message today while i was playing around with the sound files in COD. http://www.deadkowkult.com/modules.p...topic&p=55#55. Wow, thought I was banned or something (I wasn't). There are many on-line suggestions to fix this,

I tried it but it didn't work. Heres how I fixed it. Some other posts suggested to uninstall the game entirely. what I did was right click on the game in STEAM and chose --> delete local content. Then look under the steam games list, and under "not installed", right click on MOW2 click "install game".

It seemed like it was going to download the whole thing but it was done in 2 seconds.
