If your license is already on your ilok you will have to go into iLok License Manager and move your license from your ilok to your PC manually. You will do this by following these steps:
1. Plug in your iLok
2. Load iLok License Manger and log in with your username and password.
3. On the left hand side of iLok License Manager, click the icon that corresponds to the iLok which contains your license.
4. In the main window, find your Blackhole license. Click and drag it onto the icon on the left hand side of iLok License Manager the corresponds to your computer.
5. Follow the dialog boxes.
That said, this might not work just yet. Apparently the change to switch existing licenses to be able to be authorized on the host is still percolating through the servers. It should work later today, but I'll let you know.
