I am no CoD4 expert but I believe you need to download the patch for version 7...you appear to be running version 6. I think that is normal though because version 6 is that last version they produced to be distributed to stores. Version 7 only comes as a patch. To top it all off the patch is hard to find and, last I checked, could not be found on the official CoD site. I am sure one of the more regular CoD4 players around here will be able to help you out though.
