I've been getting your error ever since I installed RaceMenu (the "Invalid Chargen script version detected (2) expected (4). Error Codes: (10) " part). Error also pops-up during the loading screen when starting the game. I simply click "OK", the pop-up goes away and I've until now never had any problems with the mod, whatsoever... Have you tweaked papyrus? watch a video named "stabalizing ( or however it is spelled ) Skyrim" by tweaking it properly you'll avoid the ctd issues. P.S. it does not totally kill the CTD attacks but it just stops CTD attacks temporarily... I think CTD occurs every 3 day straight of playing, I don't think you'll play that long though.
