No accounts with the Admin role have been found...

We have a new Organization account.


When one of my developers archives an app and tries to upload it to ASC, he gets the following: "No accounts with the Admin role have been found..."


In ASC he clearly has Developer role with access to Certificates, Identifiers & Profiles.


He can also build and deploy the app to his own device fine.


Any ideas what is going on?


Help is much appreciated!
