Solution:
If you are asked to re-authorize or if your authorization code does not work, it is likely because your computer ID has changed. The computer ID is based on hardware parts in your computer and the most common reason for the computer ID to change is if you have made any changes to your hardware, in particular disabling your network device or wireless modem. Or, of course if you have installed your product on a new computer.
Other major changes such as replacing your motherboard or internal harddrives could also cause the computer ID to change.
Different computers would have different computer IDs, so you will need to authorize your computers individually.
If you are having problems authorizing in your host, we suggest you download Toontrack Solo and attempt to authorize using it, instead of your regular host application. The Authorization will carry over to all applications once performed successfully.
