License activation

Hi Clifton,
I'm asking about this on behalf of a friend from Italy with whom I work frequently. He uses Toolbook 10. TB license activation does not affect me personally as I use 9.01. Acoording to this http://tb.sumtotalsystems.com/kbfiles/kb/ToolBook%20Knowledge%20Base.html?ProductActivation.html it seems that with one license it is possible to use Toolbook 10 on 2 different computers. However before using it on one computer my friend has to deactivate the license on the other computer. Is this normal? My Powerpac license allows me to use 2 computers simultaneously if I choose but maybe the licensing system is different? I've never tried to use it on 3 computers but presumably this would not be possible.
Another question: what happens if the hard disk breaks down? In this case deactivating the license would seenm to be impossible.
Thanks for your help
John
