Scott on of 'Registering', 'Authorizing' and 'Computer ID'.

Toontrack has an extensive FAQ that covers many issues and questions.

http://www.toontrack.com/faq/

Specifically:

1) http://www.toontrack.com/faq/w.....mputer-id/

2) http://www.toontrack.com/faq/h.....oducts-on/

I would also suggest downloading Product Manager to make the authorization and installation process easier.
