I emailed them a few weeks ago and asked them if they had a demo version.
They said no.
They emailed back about a week later and said “Look! We have a demo version almost ready for the public. Would you like to try it?”
I downloaded the demo version and it immediately crashed.
I sent them the crashlog(s) and they said they would be back in touch with a version with debugging enabled to try to see what was happening.
Unfortunately, right around that time, COVID-19 happened.
So I would suggest hanging tight for the time being, as there will most likely be a trial version made available to the public once things settle down a bit.
If you wanted to do something in the meantime, you might contact them though their website as I did. Perhaps they will make the demo available to you as well.
