After looking into this plugin, I decided that it will do what I was looking for so I went ahead and bought it so I can use some of the features in the Premium version that I wanted.
However, after I create a license for my site and try to register it from the plugin in WordPress, I get the following error: "License validation failed. Please verify the key configured by you.".
I've tested it on my backup/testing site and my live one and get the same error with both. I have tried 3 different keys that I created as well.
Sorry to post here, but I've tried the contact form on the site and also Facebook, but haven't heard back. I was wanting to get this working by this weekend as I expect a lot of traffic to my site and want this working for it.
