These pdf's were made by me with Adobe DC or something. I can open the files, but not save after changed texts in them even one character. Always when I try to save the new version I get a comment "Range check error". Tried also to covert the pdf's to Word format but most of the texts were not there in Word document. What to do?
If I open a pdf in my "normal" files I can save and change it without a problem. First saving the pdf sent by outlook to some folder and then opening it changing and saving results the same "Range check error" text.
