Unable to open document
Hello,
I've created a document that I was successfully opening yesterday. Now, when I try to open it, either from the desktop or from the app, I get the following message:

System and OS: PC, Windows 10 Pro V1803
File size: 1.2mb
Strangely, when I renamed the file, I was able to open it on my MacBook Pro. But no luck opening it from my PC hard drive.
FYI - the cloud isn't working for me (an Adobe tech was unable to resolve this issue), so I'm currently sharing files between my machines using Dropbox.
