Technical Difficulties

I told you guys I was going to make a few sims 3 series/movies, but it's going to take a little while. I have the game on 3 different computers, but it only works on 1 of them. The 1 computer it works on isn't mine so I can't use it that often. What I mean by the sims won't work is it won't open. Not even Origin will open. If you guys know a way to fix it other than reinstalling the game, please leave a comment. It took me HOURS to download it, and I don't want to go through that again.
