The worst possible licensing system and the only one among over 60 paid apps, having this problem. I tried working with the developer but he just doesn't care. I have to repay for the LIFETIME license EVERY SINGLE TIME there is an upgrade, in order for the app to recognize the previously purchased license. I also paid for the PRO key, which was also not recognized!!! Horrible, appalling and outrageous! The day I'll find a decent equivalent I'll abandon it and never look back. Reply: which part of I paid for both, TWICE because none is working, you don't get!!!??? I know to read a menu, thanks, it's just not doing what's supposed to be doing. It's you, forcing the license verification after each update!
