I clicked on an update option which did not indicate that it was to High Sierra, but apparently I have it. Whatever the update was I'm now unable to use inDesign. Photoshop and Illustrator seem okay.
I'm using CS4. I can't do Cloud so I'm hoping to find a solution to get it working again. Any existing file I've created comes up as a tiny box in the upper left corner with a blank canvas, and when I try to open a new document the options screen is also blank.
I've tried repairing inDesign preferences but nothing changed. It seems the only other option I have is resetting to Sierra which is not something I'm too excited about trying. I have things backed up,but still. Is there anything else that could have caused these problems that has an easier solution?
