Had to reinstall stamp manage 2017 via disk, due to computer crash.I recovered data from backups on computer for 2019 but I think it is only a demo as I can acess stamp manage without using activation code. How do I get a code to work?tech help is never on line when I check The problem is all codes that I use do not work, I tried to do a backup from internet but this option is not available, did not use a disk for 2019 but downloaded from site,(at time of purchase) this setup will probably stop working at 30 days.Any help for this problem?this is very frustrating
