The license URL doesn't work anymore, and searching the site doesn't return anything useful about licensing LMS.
Has licensing changed? I don't have a PAK only a s/n now.
http://www.cisco.com/go/license is redirecting to https://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet fine for me. But since you don't have a PAK, you may need to email [email protected] for further assistance.
