Can't get to "invite collaborators" form Portfolio --> settings or Resources --> invite collaborators

I am not able to get into the "settings" menu from my "Entrepreneur" portfolio. It gives me this message when I click on "settings":
"user credentials not present or invalid"

I have tried logging off and back in. I have tried clearing browser cache/cookies/history.

I have also tried to get to the "invite collaborator" screen from resources-->invite collaborator. Instead of brining up the collaborator screen, it brings up the frame of the collaborator screen with the rarewire library screen as its content.

I was able to get to my "invite collaborator" screen from a different portfolio in my library; but that isn't the portfolio I need to have the developers access :(

Any help would be greatly appreciated.
