sims 3 70's 80's 90's not working

Just bought 70s 80s 90s stuff...Sims 3 will not play it.  When you play it, it will open other "stuff" (Diesel, seasons, etc.)  I even uninstalled every other expansion pack.  Now when I run 70s80s90s, it just runs Sims 3.  I have also uninstalled and reinstalled 70s80s90s.  Still no good.  I cannot uninstall/reinstall Sims 3 itself because I have lost the sheet with the product code (I still have the disk)

Please help if you can.
