My PL/SQL Developer license expired, I've got the new license. It works with the new, version15 PL/SQL Developer , but the old, version 14 does not work anymore
It says invalid registration, and after that the trial period is over, it does not accept the new registration serial number, and does not start.
I don't like the newer, PL/SQL Developer 15, because the sluggish UI, gray and black icons, and I need the version 14 to bring back.
Does anyone has a solution for this?

If you send an e-mail to support@allroundautomations.com with your current license information, we can send you a license key that is compatible with version 14.

Problem solved, thank you,
