Sims 2 Legacy : 'Application has crashed, application will now terminate.'

cant even play the game at all anymore because of this!! first, the game deleted all my CAS families, so i started playing premade families just to get my moneys worth...now i cant play at all...get this error every time i load into ANY household. I have a brand new $3,000 gaming computer as well... should not be happening. I'm insanely upset....been way too patient with EA
