I also have the same problem.

In debug mode i get this:
Notice: Undefined variable: mosConfig_lang in /home/e-smith/files/ibays/ringtones/html/components/com_comprofiler/plugin/user/plug_cbcustomizetab/customize.php on line 14

And when i go to my sql screen in phpadmin i insert the lines:
UPDATE jos_comprofiler_fields SET `table`='#__users' WHERE name='email';

#1060 - Duplicate column name 'registeripaddr'

Hope there is a fix ?
