I get the error message "Could not access Acrobat's web capture facility. Acrobat may be busy or waiting for input." I have Win 8 OS also. Is there any way to convert?
I doubt that PDF Maker of AA X will work in OFFICE 2013. You should be able to print to the Adobe PDF printer, though I am not sure how AA X works in Win8, another potential problem.
For a web site, you should be able to open the web site directly in AA X.
