My Sims 2 Seasons Window Won't Close Out!?

I was very impatient of my Sims prgnany, so I use a ceat to force her to give birth that was titleed CINEM BABY or something like that. She was giving birth and then there was an error pop up. I couldn't move the cursor at all. I ctrl alt delete to minumize it and to close it from there, but it would not work. I even took the disk out and it is still present. How do I get rid of it?
