Blank file when i extract

I have installed as admin, run as admin, all seems fine. Then when I extract the save file from the flash drive and put it in a folder to work with, it is a blank page for the icon and it is impossible to use, edit or open. when I try to open with my Diablo 3 editor, it cant even see it. This is happening on 2 different computers with different OS, win8.1 and win10 anniversary edition. This all was working 2 weeks ago. ANY IDEAS, SUGGESTIONS, RECOMMENDATIONS, ANYTHING would be greatly appreciated.

Thanks in advance fir the help.
