I can't load my saved file?!

[HerLittleMajesty]

I was playing sims3 the other day on my laptop and when I went to load my saved file, it said "Cannot load this save game. It may have been saved with expansion pack data that is no longer present on this system."

This is weird because it's never done this, and I haven't deleted anything. Nor have I tried playing without an expansion pack" suddenly ". Is my saved file corrupted? Is it salvageable?

Please help, it would be a huge pain to have to start over!
