Can't open InDesign CS4 files in CS4 on Mac
My CS4 has worked right for years but today InDesign CS4 suddenly can't open InDesign CS4 files or create a new document.
Nothing has changed in the computer, no new software or plugins. All other software & hardware working as normal. The dialog box for opening files comes up, but when I click to open, the box disappears and nothing more happens. On creating new document, I get an empty box in the middle of the screen, nothing to click.
Using Mac with OS 10.13
Strange!
