No just go to help/utilities/activation options.Just deactivate that machine and it'll release another activation code at PG for you to use.
And, we've already been told on this very forum somewhere that the deactivate/activate thing has no limit.
If I have to carry my USB drive to another machine and location, this is how I intend to do it. When I leave, I'll deactivate before pulling the plug, to keep that "extra" activation ready at all times.
Anyone complaining about that may really be complaining about ue of the program that is outside of the Licensing Agreement, installing on friend's machines, etc.
I cannot blame anyone for locking the henhouse in order to keep their chickens...
