Adobe Acrobat Standard 6 – Save As error 109

I have an XP Pro with SP2. I have Adobe Acrobat Standard 6.0.

I can do Save on this Adobe, but when I do Save As, I get an error saying:
“The document could not be saved. There was a problem reading this document (109).

I can clear all registry entry for this application and re-install it, but I’m hoping that there’s another way around it.

Could anyone please help me resolve this issue.

Thank you.
