I just updated ALL Adobe Creative Cloud apps a few weeks ago. I used InDesign to make an interactive brochure last week- no issues whatsoever. All pages were "placed" directly from an existing multipage AI file and it worked perfectly.
Today I tried to create another almost duplicate brochure from last one using an almost identical AI file from last week and I kept getting the attached error, even if the file wasn't a PDF but an AI file. All settings are the same as the last file I was able to create successfully. I even tried saving the AI file as a PDF but still got the same error. Any insight on this issue? I've never had it happen before.
