My custom KRPano templates - not working - legacy stuff

Hi, I have many custom made templates from several years ago that I use, they're great for my purposes. I just drop the files on the MAKE VTOUR (MULTIRES) Droplet and it makes a nice multi-node tour with customized features. I have a 2017 Intel iMac that I use an old version of KRPano on, to be able to use my custom templates. The version of KRPano I usually used was 1.19-pr16, it was always working. Then I updated OS from 10.14 to OS 13 recently, (ugh mistake). Now the droplets (templates) are not working and KRPano Tools icon is grayed out. I've installed KRPano 1.20.9. The KRPano default (MAKE VTOUR Droplet.app) works, but I need to use my custom Templates/Droplets. How do I put this all together? Thank you. Janie
