I am the editor of a monthly news letter for an organization and create it in Publisher 2016 and save it as a PDF so my members can open it. I have a hot link in Publisher the works fine, but when I try to open it in the PDF version I get this message:

I have deleted the PDF and saved it again to see if that would fix the problem. It did not. I rebooted and tried again, same issue. This happened last week in an Outlook document when it blocked the National Anthem!
Microsoft support was useless and said Publisher is a commercial application and commercial support is closed on Sunday.
Does anyone have an idea how to fix this issue? If so, it will be greatly appreciated.
