A million thanks to those who identified this as a machine-hardware detection issue, and a MILLION aw-shi?'s to the TTax developer team for testing license locations this way.
TTax AGAIN demanded a re-activation today (about the 10th time on this, my only TTax pc). I have a hot-swap backup bay. Read these messages, ejected today's backup drive, and TTax launched happily without demanding re-activation.
Thanks, community!
