JOOMLA SEF for JOMSOCIAL

THIS IS URGENT!!! TIME FRAME: Within a few hours. PROBLEM: I have a Joomla site version 1.5.22. I recently installed JomSocial component on my site. I am using SEF Advance version 2.4.4. I need the following changed in the SEF, but don't know how to do it. Current URL with SEF: [login to view URL] Need to change it to: [login to view URL] I am trying to change the URL name from 'jomsocial' to just 'social'. I have tried to change the component name in PHP MyAdmin, but that did not work. I need to fixed asap, and the changes cannot effect how the current SEF is setup on the site.
