I have been through this article (https://jorgequestforknowledge.wordpress.com/2015/03/08/resolving-the-pwunrecoverableerror-error-with-fim-self-service-password-reset-sspr/) and still getting the same error. 

At a bit of a loss now. Hoping someone could shed some light on this and help me out.

Thanks
