I'll dig up the files and add it to the first post. I even thought about doing so from the start. Fortunately, the process is the same.
EDIT: Done. check bottom of first post. Please let me know if they work, as I don't have COD4 installed and could not test it.
As it turns out, PB dropped support for about 10 older games such as Far Cry 2, Quake 4, and more. I found a place to download the latest PB files fro ALL the games they decided to drop, so if there's interest, I can post it.
