Can't delete users

Having a problem on a site where I have installed Communuty Builder 1.7.1.
Joom version = Joomla! 1.5.25 Stable [ senu takaa ama mamni ]

I'm getting this error when I want to delete someone:

DB function failed with error number 1146
Table 'joomla.jos_community_users' doesn't exist SQL=DELETE FROM `jos_community_users` WHERE `userid` = '806'

Τhat doesn't look like a CB issue as that is not a CB table.
