Great! Just great!

I came back on Sims, and it has been a little while, and...
Everything is gone.
Everything. All my houses, characters, gameplay. All of it. It started off like I hadn't even played the game.
I'm sorry, what the actual fuck. I spent ages getting all of that set up, and I mean ages. I don't even have my saved households! ARGH!
What is this?! I want to fix this dammit! I want everything back!
