Acrobat: Error - "There was a problem reading this document (8)"

@CE707070 it worked once, and now the same file is giving you issues. Likely, the file was corrupted during the saving. 

Let's try saving a different PDF file (preferably one without Hebrew text) to see if the error is specific to this particular document or a general issue with Acrobat. If this works fine, now try simplifying the Hebrew document by removing any unnecessary elements, complex formatting, or special characters. This might help isolate whether those elements are causing the issue. 

If you have access to the original source file of the Hebrew document, try recreating the PDF from scratch using different settings or a different PDF creation tool. The Hebrew text might contain special characters, complex formatting, or right-to-left writing directionality that Acrobat is struggling to handle. So, make sure the OS and Acrobat is set up for that

When the time comes to export the PDF, make sure you embed the fonts and the fonts are compatible with Acrobat. If necessary, try installing the fonts on your system.
