Can't open file?

[Phantom Demon]

I have Pyware 3D installed on my home computer.
I saved my drill to a thumb drive
I install Pyware on my school Computer
The program works fine; however it will not open the file on my pin drive. I can't show the file to my students.
I have tried different school computers, Installed as administrator, emailed the file to myself, used a disk, etc.....
Why can't I open this file?

When you are trying to open the file are you receiving an error message. Also are you trying ot open the file from within the program through the File>Open File option.

I finally realized that the file I had created was with a version that I had run updates on. Once I ran the updates on the other machine it worked fine...duh.
