Missing Plants in Sims 2

Thanks for getting in touch with me.  Yes the plants and other objects from inside the game went missing from buy, and build/buy garden.  Like the small cactus everyone smells, the big cactus, weeping willow and so much more.  The hydrangea shrub.  It happened when first I deleted Straingtown from my game and installed one of those cleaned up versions, but I put it under something other then downloads and I know I did not do it right.  The first thing I noticed in the game was anything that was on a lot in Straingtown was now unusable and also missing from the catalog. Telescopes, easels and so on.  I then got rid of that town and kept playing other hoods but hate all the stuff being missing.  I finely uninstalled and re-installed my game in hopes that would bring everything back.  I got Straingtown back but not the stuff.  I have got much of the stuff back off sights on line, but not my garden stuff or lots of plant items decor and garden from the mansion and garden pack.  I have the ultimate collection.  I know I messed my game up but would have thought reloading it would have brought it back. Please help if you can.
