Error when sending mail.

I have Adobe Acrobat Pro?9.1.2.

After installing the latest update, I can no longer send email from Acrobat.?When I try to send the PDF via email, the message says '' an error occured while sending mail''

This?feature worked fine until I installed the update.?Any help would be appreciated.
