laser702, you may be right. It looks like windows 10 was also updating something around the same time. In any event, I decided to go ahead and reactivate TT H&B. Since then, I've opened and closed the program a few times and gone through yet another TT update with no issues. It remains activated (crossing fingers - for no more glitches). My main concern, BTW, was that TT would repeatedly demand new activations until it would accept no more, and the app would be unusable. Without going through "Support Hell" I'd love to hear from a qualified tech person who knows more about this.
