Ok so this is not to ask for help, but I have found the solution to a problem that I had

before with the sims 2 collection packs!.

I remember that people always sent me to sims wiki and I would be going back and forth with the official sims support, but none help. Also I was told to download cc cleaners, they're no use to me.

Ok you may have this problem

You have uninstalled all expansion packs and then you reinstalled, but there is a problem!. you can re-install some of your

expansions except your collections packs. You have googled and posted yet no one helps :'(.

So I had this problem before, and I figured this out myself and fixed my game.

Here is a little guide that I made to explain how to fix this complex problem.

Registry cleaners allow you to do just that!

Thanks for that, we have some more detail here:
