We are asked to do the LEED consultancy for a project which had been registered previously by another LEED consultant (admin). However the Project owner doesn't have the login to the LEED online because somehow he lost the email contains the login details and previous consultant is reluctant to share any information with the Project owner due to some unknown reasons.

What is the option available to the Project owner to regain his login in-order to change the LEED consultant(admin) to a new company?  

Or Is there any possibility to re-register the same project? 

Please note when we search the project in LEED online it shows the project as a registered project with a Project ID.

Please advice.

Thanks in advance.
