I don't have Firepower, sorry; the link came from a Google search. Keep going with the emails and make sure it's the right address you're sending them to. There's also a Firepower message board forum, you might try there.
Another thing - 180MB is an awfully big download for IE to keep standing up for, I'd use a download manager. Firefox has one built in afaik although I use GetRight myself. If you go on and download ETO (free!) you'll find it uses its own download manager to get the near-2GB package. MAW should be available again sometime, we hope; it's around 2GB as well and I'd definitely use a download manager to get that.
