Dave, when someone steal your activation key and installed it on his machine, servers at Anthropics will allow activation of the stolen key. Now, when the thief run PP on his machine, the servers at Anthropics now see two different PC fingerprints. Hence, it disable the PP license. I don't work for Anthropics and I believe that is the way how the PC fingerprinting works.

All I can say now is that your license key is now compromised. You will probably get endless problem unless Anthropics is able to invalidate your original Activation Key and issue you a completely new key.

Remember that activation code is private and must be treated as such.
