Hi bjohnst6,
You have struck a security feature which prevents licensed versions being installed on multiple systems simultaneously.
Please log into the licensed-users
Support Center and select "Contact Support".
You will need to give them details about your AAW 2008 purchase (date, registration key, etc) and your new "Hardware Fingerprint". This is specific to your new system - when you click on "Register", you will find your own fingerprint.
Click to view attachmentOnce they have this information, Support will send you a new Serial (or Unlock Key) to re-activate the remainder of your annual license.
I might also suggest that you take this opportunity to upgrade to AAW Anniversary Edition - click on "My Downloads" whilst in the Support Center and you will be directed to the download site.
Regards,
Spike
