XF 1.5 MySQL issue when trying to import users


I am trying to import a currently existing 1.5.1 XF install to a new 1.5.1 instance and when trying to import users, I am getting the following message:

Mysqli statement execute error : Duplicate entry '2' for key 'PRIMARY'
I seen some other thread saying something about add-on data that is causing this.

Is there anyway to get around this? We are looking to import the site in and start fresh with less add-ons.

Any help would be appreciated.

Thank you in advance.
