I had used Traqmate on the past 3 track events I attended. In the first event I had no problem reviewing the laps I just did on the DU. In the last two session, when I try to review the lap times, it shows "NO LAPS" on the DU, even through on detail section of the session data shows there is data there. But the laps show up once I download the data to TraqStudio. How come I've lost the ability to review the laps on DU?
