Hi ,
Our company has bought one commercial copy 10 months ago, “Order #3793 was placed on 2016-12-01 and is currently Completed”. And it was v1.6.
When I click the download link of v1.9 in the orders page today, it says, “Sorry, this download has expired Go to shop”.
Normally I would expect of 1 year software maintenance of free upgrade for the 249 dollars paid. As for your plugin, do I need to pay again to get upgrade?
