I'm getting this error on the final step of the import wizard.  Didn't find anything searching the site about it, anyone have any ideas about how to solve it without the source code?

Thanks,

Thanks for the reply David but looks like I have no dups in there.  Thought it might have been because I mapped the email and was using the email for the username so I changed to first name last and get same error.
