When I first got mine with my accutrend spirit combo, I did. It gave lovely graphs to show the DSN. But the downloads of the useful figures (ie bg tests, carbs, bolus and basal rates) were downloaded in a way that was totally unusable even for a geek-it took me 5 or 6times as long to manipulate the data into usable/readable form as to enter it into my own spreadsheet. So when I upgraded my pc to Windows 7 and discovered that the software no longer ran, I wasnt too upset-gave me a reason not to use it. It may now work (upgrades do keep being written), I just cant be bothered with it-my DSN never understood the reports it gave anyway, so why waste the time on it?
