Sorry to hear about the trouble.
When you said that its not working, then what does it mean? Is it not giving the conversion page or after converting giving any error message?

Thank you for your e-mail. If I said „its not working“ it means I was log in to acrobat, I had open the PDF file, on the right site there were the options, and when I clicked on „Export PDF“ it showed me „another information“ and I couldn´t transfer it to Word. Please see below printscreen. Left site.
I cant see the attachment here, but as you said its Adobe Acrobat so I could understand what could be the problem.
Adobe Acrobat doesn't support the Export PDF subscription. You need to uninstall the Acrobat Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs and install the free application Adobe Acrobat Reader DC- Adobe Acrobat Reader DC Install for all versions
