Bisher is asking about CFS3 patches not WOFF patches?
No you do not need to patch CFS3 IF it's a reasonable recent one. Anyway just install WOFF and let it find the CFS3 files from your CFS3 CD or DVD and it will check for you.
I appreciate you jumping in on this Pol, Maybe I wasn't clear in my explanation. I did say "You don't need to patch CFS3 if you have the latest version. See the "FAQ" on this at "overflandersfields.com".". I only mentioned the Patches for WOFF as an added note incase he needed them.
