Sims 3 custom content does not show up in game?

Basically, I had a saved game file with a bug in it or something so I started playing with the backup in the folder, and I copied the backup so I could have a backup for my new file. However, when i ran the game after deleting the original malicious file,all my custom content was gone. So I tried to install it again, along with some new stuff, all from TSR and other 3rd party sites. It says, "success" for each of the files and shows up initially in the installed content folder, but then none of the stuffa actully is in the game. And then if I launch the game again, the items are in downloads but not installed....help?
