Authorization Failure on Maverick? Help!

[maddbaron]

I'm trying to run update manager and when I try to update applications the authorization box shakes, says Authorization Failure then goes away. Same thing happens when I try to change my login settings.

This is a new problem, I haven't done anything to my system since I upgraded to 10.10.

how can i fix it?

Thanks in advance.
