[Blindmath] Need help with Chatty Infty Demo

[Billy Baer]

Hello,
 
I've attempted to download the Chatty Infty Demo, but I have not been able
to get it to run. I've received numerous error messages ranging from not
having fonts installed or administrative privileges. Does anyone know how to
make sure that I am using the Demo rather than the actual version I would
purchase?
 
Can someone please direct me to where I can download the Demo version?
 
Thanks,
Bill
