Using RDMS 2.2.8.0 And RDM 9.1.2.0

I have set up a RDMS on an existing RDM database.
The web UI works and i can login as user there.
But when trying to start RDM against the RDMS datasource i get this error.

System.web.services.protocols.soapexception: server was unable to process request
---> System.NullReferenceException: Object reference not set to an instance of an object at Devolutions.RemoteDesktopManager.Server.ServerCacheManager.<FilterforVersion>b

Also, is it possible to get the application to use the logged in user & password when starting RDM.
I do not want my users to need to enter the password again.
