Sims 3 Store Content Won't Download
The item you're looking for is part of the Ultimate Career Bundle that you receive when you register Ambitions with the store. I downloaded this bundle without issue about a week ago, using Firefox, and I'm on patch 1.67 from a Steam install. When you sign in at the store, does your page reflect that you own the EP? (Look on the left-hand side for a list of packs that the site thinks you own.) If not, but you've registered the pack, check your Origin library to see if it's listed there. If you don't see it, you should contact EA for help with your account.
Firefox is the recommended browser for downloading from the store and exchange, so it might be useful to use it instead. If the pack is registered to you but you still can't download, try clearing all of your browser caches, including the one for Explorer. You could also try changing your password and then login again.

If you're still having trouble, drag your entire TS3 folder out of Documents to the desktop and rename it. Then launch the game; a new, clean folder will spawn with no content added to it. Try downloading to that folder. If it works, you can transfer your old content to this new folder afterwards.
Just a note, sometimes the store site doesn't work for a couple of hours or even a day. Nobody knows why, but it usually fixes itself eventually.
