Unfortunately HM3 Apps can only be used if you own a HM3 license. They can not be used if HM3 is in Trial or Free mode. This is a security restriction of our licensing system. The only way you can try that App would be to buy HM3 and use our 15 day no questions asked refund period as 'Trial' time for testing the app.
If you actually own a HM3 license already and can not activate the NC Trial/Free version: Please create a support ticket via the
'Contact Support' link with a link to this thread and your forum username. Please reproduce the problem and attach
a set of log files and a screenshot and detailed description of the issue in the support ticket you created.
