The Import from Registry process is far from perfect, purely because there’s not enough human-readable (or obviously decodable) information presented there to generate a workable set of ‘sites’.
Think of it as more of a template to work from if you’re installing bounSky on an existing machine that you’ve already used to sign in to multiple sites or user accounts.
Essentially, all I can reliably pull from the registry is the user’s SIP address. I can usually also retrieve any Manual Configuration values – but not the value of the Automatic/Manual radio button.
Note that an Import (whether from File or Registry) will over-write any previous configuration without prompting.
