Lost Hub Log On Password 

How do I go about resetting or recovering a lost Password for my HUB? I travel a lot and have misplaced my log on ID and password. I wasn't able to really get familiar with the HUB before I left. Now the HUB displays a completely different log on window that shows "Castle OS" and the password box. Also, I keep hearing about a license code.. Do I need one for my HUB? If so I have not received one. Please reply by private message or post here in case there are others out there in the same boat. Thanks Chris.
