Need help for uninstal verification for sims 3.?

Ok so I decided to add the sims 3 to my sisters laptop because I decided to vacation in Australia and as I had never been on a 21 hour plane ride (total) just to get there, I decided to add it to help kill the time on the plane. Long story short I don't need the game anymore and when I went to uninstal the game from her laptop the game gives me an error along these lines: deleting the games may cause me to lose my saved progress and that if I don't want to lose my saved progress (so far) that I should return my sims to their home town (weird) then save them at their home town and then uninstal.

Well this makes absolutely no sense whatsoever as number one, my current sim and his family (parents) ARE in their home towns (I haven't made them move towns at all, only homes) and I never even tried to load or play the game on my sisters laptop. So you can imagine my confusion upon attempting to uninstal it on her laptop when I haven't even played it. I do, however, have the sims 3 and the current expansion packs on my own desktop computer which i do play.

So my question is if i do choose to delete this off her laptop (which I will because I won't be needing it anymore) will I lose my current saves and all the data when I go try and load the saves on my computer when I go to play? It doesn't make sense that I would lose my games just by trying to uninstal the games off another computer, especially since I've never had this error before (not that I can ever remember). And I receive this error for the base game and every expansion pack that I own. Any confirmation on whether this would be safe or not would be great thanks!!
