Squarepants

I just bought Optimize yesterday, and cannot complete the registration. I pasted the license key I was given, but when I click "register," I get an error stating that the license information is incorrect. I tried using customer support and was routed back here. A similar problem described on another user's entry a couple weeks ago listed a link for support, but when I sued that link, I was told at that site that it no longer can be used. Now what?
