Storyline 360 won't allow me to open a file copy
This morning I tried opening a Storyline 360 file I've worked on for the past 2-3 weeks without problems. I got this message: "The file ... is being used by another process or you do not have the proper security permission to access this resource. Make a copy of your project file, then try to open the new file." I made a copy of my original file, but I get the same message when I try to open the copy file. No one else is working on this file, and I don't have any other software programs open. Can anyone help, please?
