My game keeps getting the code error 12 and will delete my entire game

After years of play my games keep getting deleting under this error and wont let me save and just wipes out all of my saves. why is this happening? It has happened twice in one days and I spent 7 hrs trying to redo some of what I lost. Have I just wasted my money on buying 10 sims expansion packs and years of play? I am about to never play again and you will lose a valued customer.
