We spent $210 for the developer version of this plugin. From the start we had issues with getting it to work correctly. Namely it was not properly saving settings in the admin, it was sporadic when rendering packages on the front end, and we were repeatedly getting a “link expired” error after using a download link despite not setting it to do so. We attempted several “fixes” provided by the author’s support team, including the immediate updating of the plugin during all this due to a bug we discovered.
After 3-days of trying to get the plugin to work we decided to go with another solution, and requested a refund. After a considerable amount of back and forth emails from the company that developed this plugin, we were told the only way they would issue a refund is if we provided them access to our admin control panel to see if they could determine what the issues were. This was completely unreasonable to us as it is a well know fact you NEVER give your WordPress login details to a third party.
I would highly recommend only using the free version of this plugin, and do NOT pay for the Dev or Premium versions of this plugin. If you have compatibility issues, and do not wish to allow them access to your admin, they will REFUSE to give you a deserved refund.
