If Firefox is blocking popups, the download will fail.When Firefox asks you what you want to use to open the download, choose the entry that says simply 'The Sims 3' (the base game, not a pack) and has a green plumbob next to it.Sign into the store, and go to Hidden Springs's product page directly:.Open the launcher, but it's not necessary to login (I didn't, just now).Clear Firefox's cache, if you haven't already.I tried downloading Hidden Springs a minute ago, and it worked fine for me. But you should be fine if you get just the right combination of steps. Downloading on a Mac can be tricky sometimes I have one too.
