I highly doubt customer support is ignoring you. Lone Wolf is very, very good in that regard. Have you tried the email address on the website? And have you checked your spam filter to make sure the reply didn't accidentally land there? Rob, the president, is fairly prolific on the forums, but
support@wolflair.com is still the best way to make sure that your situation is properly handled.
Unfortunately, I suspect that they're not going to upgrade you to the newest version for free, but they can likely get your older version to work again. *shrug* But I'm just a fan, not an employee, so take my words solely as my opinion.
