Expansion packs not working in game

Hello everyone, I'm new to the forum. Registered because I'm having a problem with the game which I wil ldetail below.

So I downloaded The Sims 3 Complete Collection that was uploaded by you guys a year or so ago and the game plus all the expansions were running perfectly at the time. After a while away from the game, I tried playing it again yesterday, only to get an error message saying I had to reinstall the base game and it wouldn't let me into the game no matter what I did.

So I followed the instructions in full for the Ultimate Fix given here and this fixed the main problem I had and let me into the game again. However now none of my installed expansion packs are showing up on the launcher and the content isn't available in game. Instead they show as greyed out and hovering over them it says it "requires" the expansion, when its already installed.

I've run the Ultimate Fix a second time to see if that fixes it and again the expansions still don't show up. Does this mean I'm going to have uninstall and redownload all the expansion packs in order for them to show up in game? Or is there a quick fix that will fix my problem? Reason I ask is I moved since i downloaded the complete pack inititally, and I have more limited internet where I am living currently, so I don't think I'd have the bandwith to redownload all the expansions a second time. 

Thanks in advance to anyone who can help, and sorry if I'm asking something thats been asked a million times before.
