I did the same thing, and they responded with a form email after 3 weeks, and never resolved the issue, but closed the ticket. Considering the amount of money I have shelled out to this company the level of support is staggeringly bad.
Actually I tried using a private browsing window, which doesn't restore sessions, same error. I have also tried Chrome, both normal and incognito, the dreaded Internet Explorer on a different PC, and Silk on my Kindle Fire. All redirect improperly, except Silk, which says the page has been moved.
