Premium license keeps deactivating

Curax the software company that makes this plugin is sadly not supporting this plugin for this fault. It has been an issue for over two years. In fact, if you look at the age of the topics they are not offering any support full stop. There company support page is inactive and despite asking for a refund for a faulty product requests are ignored. I will be talking to the credit card fraud department.
