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

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
