You can subfolder bodyshop content if you have the Nightlife expansion, but as your profile says you don't have NL that's why Jaxad says that. Make sure you have custom content enabled, and definitely definitely read the FAQ's, it may seem rude but answering such a general question as "I need help, my downloads aren't working" takes about 5 pages to respond to all the possible culprits. The FAQ's here are excellent, you'll see a lot of effort has obviously been put into them and hopefully your problem will be solved.
If you're still having problems be real specific about what you've done (or haven't). Another future reference thing, "help me!" doesn't make for a good title, it doesn't let the people scanning the thread know your problem so you may not get folks familiar with that problem to read and reply; and they know you need help or you wouldn't be in the "Sim 2 help" forum.
. Anyway, too much on that, if you read the sticky titled "read before you post" it's all in there
