I bought and installed the product, but I am in trouble because I can not read the data created with the demo version “Lock” is displayed in red and I can not load it
The demo version allows you to test all features of the software whereas the type of license you purchase limits the features you have access to.
Because of that you cannot import the data from the demo into the paid version.
hello, the restrictions of the Demo version are listed here: https://www.capturingreality.com/Product#Download
Thank you for your infomation. 
you are welcome
