New Post: Error loading TreeService at login after upgrade 4.x Beta to Released 4.0

I've run into a problem where whenever I try to login to C1 console after a new deployment I get a popup window with the following message:

You have not been granted access rights to the system. Please contact your administrator.

If I click "ok" and close the popup and hit refresh in the browser I get logged in and everything works fine.

If I check my server log I have this in my log:

System.NullReferenceException: Object reference not set to an instance of an object.

  at System.Collections.Generic.List`1..ctor(IEnumerable`1 collection)
  at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
  at Composite.Services.TreeServices.GetActivePerspectiveElements(String dummy)

Any solution to fix this?
