Not Enough Rights error in Journal Tab of Terminal

[Tim Barnard]

When I try to change either my master password or investor password, the change fails and I get a Cannot change password [not enough rights] message in the Journal tab of the terminal.

 What is causing this. I know the current master password is correct because if I key in anything else for it the error message changes to Cannot change password [Invalid account].

So what is causing the terminal to say I have insufficient rights?
