When I get the error message, the thing to do seems to be to click the OK button, close the PDF, reopen it, then close it again. After that, I don't get that message again, even if I do further editing and saving to the PDF.
This is usually caused by incorrect byte serving of the PDF. If you turn off byte range requests, by unchecking the Acrobat prefence, Allow Fast Web View, it should make the error go away, although viewing of the PDF will be slower.
f you have inserted graphics from different graphics programs, for example, or from different users, one of these may be causing your problem. To test this, create a copy of your document with all the graphics removed, then add them back in one by one.
