Comunity Builder Bug Fix

I need a bug to be fixed in one of my website http://dieselship.com. 1. In this website you can find Community builder 1.2RC2 installed. In this CB i have added more fields in registration process (say College studied , Date of Birth, Company etc..) the problem is when ever i activate these extra fields in CB i get error , while any user sign ups or even registered user try to login to the website. But Registration and logins are working fine with default joomla login module. Initially the sign up / login process was working fine ( with CB extra fields) but it was unstable and failed working after few days. So i installed a fresh joomla and installed CB again in another path [login to view URL] So you need to fix the bug only in this folder path i.e [login to view URL]
