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

I do  as well and on top of that my game is full of bugs and unplayable in certain ways :(

Update:
Now it crached even more, I make family with dog and then when I move in dog disapears, there is certain things from game that are missing which I do remember that I has when I was a kid and using my discs, my sims age super fast that it's unplayable (like what the hell), for my dog (schold or praise) is not being saved or progressed at all... and many many more bugs...
