Thanks to George & those who’ve responded so far. In my Premier Pro auto-save file, the file icon says EN.It has the name of my project and .prproj. When I click on properties it says:
Type of file: PRPROJ file
Opens with: Adobe Encore
When I click on it, it tries to open the file in Encore and then gives the message I wrote earlier: “cannot open file…”
So it’s kind of a Premier Pro/Encore hybrid file…Any other ideas or suggestions? Thanks!
