I was using the online Cisco license registration wizard to get a few licenses from the PAK's I recieved via mail but I made a mistake. When I went through the registration process it asks you for the Serial Number / Host ID. Well I looked at the unit itself and wrote down what I thought at the time was the serial number. Come to find out it's actually different. I tried to go through the registration process again and of course I was unable to. What do I need to do to get the PAK's unregistred so I can go through the process again or is their a way to edit the license file itself?
