My Sims 3 Game Won't Finish Loading and Other Problems --- Help!!!

A little late in the game, but I'm hoping someone can help. The saved game stopped loading with a small fraction of the bar left and the little phrases below stopped changing, but the music still plays so it's not frozen. I've followed all the steps above—moving folders around, deleting the specified cache folders—and my game worked that night. But I've come back tonight to play and now stopped loading again. Any help is welcome because this is really frustrating.
