error Acrobat PDF files is having difficulties. File does not begin with %PDF
I have an AI file that won't save. (Windows 10, Adobe Illustrator 2018 CC)
Every time I try to save as an AI file I get an error message saying "Acrobat PDF files is having difficulties. File does not begin with %PDF."
It does not include the piece about file being named wrong or other options I've read about, just that it's having difficulties.
I've looked through other forums and have tried all of their advice, none of which has worked.
I refreshed preferences. I've changed fonts, tried to save as EPS (crashes), changed the file name. I unchecked the box that creates a PDF when saving as .ai. I saved the file in parts with a new name, some of them are opened, and some are not.
I wrote in support and they answered me "There are multiple factor both internal and external to application that can lead to document corruption . The file can get corrupt due to multiple reasons associated with the file itself like the links used in the file , the styles , fonts or any other."
Any other ideas?
