The Sims 3 Wont let me move to another house...why is this?

Alright, My game works until I select the house I want and everything and I'm back in the main menu and I click accept, then it asks me if this is my household, and I click yes, because it is, then it loads, loads, loads, and loads... But it never stops loading. Its been about 4 hours now.. I tried cleaning out my computer and restarting my game and computer, it still don't work. PLEASE HELP!
