I do, duh. Does anyone look at the picture I posted?
Yeah, I think it's some sort of incompatibility - turning off forge throws off the OF error, but no mods without it. Gonna use another edition, I guess.
Edit: Optifine AA+Smooth A7 and Smooth A6 both crash the game even earlier, throwing not one, but 3 errors.
Exactly, I have:
-- Jar mods: Modloader, Forge, Optifine, Code Chicken Core, NEI Client, Rei's minimap -- all in that order
-- mods folder mods: Redpower all parts, computercraft, IC2, NEI redpower plugin, WRCBE all parts.
