A page or so back, I mentioned that I was getting a 'non-critical core mismatch' message whenever I started up TS3. Well I remembered reading on this board that someone had added .cfg to the end of their resource file (since altering this file re-names it to resource instead resource.cfg) and so I tried this, and guess what? No more 'core mismatch' message.
I don't know if it will stop people's games from shutting down like some have mentioned when getting this message (I never had that problem to begin with, so I can't speak for those who do).
