Error Jmail not found [solved]

[ozziemate]

Hi,
Joomla 2.5.8
Custom template
latest Poca Download 1.3.9

I updated the software in the hope of fixing this error recieved any time I upload or download a file to and from the software.
I have two sites effected by this problem.
the error reads:
Fatal error: Class 'JMail' not found in /home/www/rebuild.chelsearotary.org.au/libraries/joomla/factory.php on line 770
I believe it woud be an easy fix but can not discover how to..
any help appreciated.

This issue has been resolved.
Apparently my server migrated and missed copying key files across.
