Boone,
Not sure if this is more recent then the steam chat you sent me or not, but also do this "2. Have you tried re-installing DoD:S or verifying the integrity of the game cache. ( To do this right click DoD:S in steam, properties, local files tab, and click Verify integrity of game cache make sure you restart steam first)"
Check the integrity to make sure all your files are non-corrupt. I remember I had you reinstall DoDs not that long ago so maybe try this to verify. Keep me updated. And also maybe you could run an autoexec with sv_cheats 0 so that it loads every time you load the game.
