Databse Query Error on join.php

I have searched and looked over alot of related topics to this on forum, and found the error code, but can someone help me and tell what changes should I make to fix this? I can see that there is some kind of problem with 'NickName', but I do not even have on registration form and there is no value for it on the 'Profile Fields' as well.

I can attach the full text of the error page if needed.

After completing the join form and hitting Submit button, here is what get:

Database query error

INSERT INTO `Profiles` SET `NickName` = '', `Password` = 'AAAAAA', `Email` = '', `DateReg` = '2013-03-25 13:12:17', `DateLastEdit` = '0000-00-00', `Status` = 'Unconfirmed', `DateLastLogin` = '0000-00-00', `Featured` = 0, `Sex` = 'male', `LookingFor` = '', `DescriptionMe` = '
