Could just be a glitch on their server – they were having a lot of issues with the website last week.
However, if it hasn’t cleared up yet you might want to try posting your problem over on their Facebook group. There are a few staff members who post to that and they might be able to help you out (or at least point you in the right direction).

Be prepared to get a little flack from some members about “cracked” software as some are a little sensitive to anything that sounds like someone trying to get around the copy protection, but someone who can actually help will join in sooner or later.
Good luck.
