Whenever I try to launch the demo from the zip file download from itch.io, I get an error that says it's unable to read file actor.json . where have I gone wrong?

this doesn't seem it has to do with the plugin itself, are you trying to run in a browser or something like that? That is an error from simply the RPG Maker not identifying the first json file (Actor.json)

Thank you for replying but I've just gotten it to work now, I had to copy the contents of the zip folder and paste it into a new RPG maker MV project for it to function properly.

While you are here though, do you have a file for a blank card template so that people can make their own cards? I saw that there was a file called template Cards_2  but it has another character and number properties on it. I'm truly enjoying the plugin so far and would like to make more cards. thank you again for responding.

you just had to unzip the file haha
