I saw a post similar earlier. I downloaded the evaluation mode...then bought the full version. When I put in the key I got in the email, and the one on-screen, it works fine. However, when I come back later it resets and I have to put in the key every time. Nothing else that is customized (colors, cutom counters, etc.) changes. I went through the registy and tried to put my key in the serial slot (which I guess is the right one), however, it resets whenever I shutdown Logbook Pro. Obviously this is not a common problem, but is there anything I am doing wrong to try to fix the problem. -Any help appreciated...thanks.
