[QUOTE="smidge, post: 673167, member: 29301"] [USER=62974]@hale710[/USER] - I think the sensor has died and needs replacing. A number of people on this thread and elsewhere have had a similar issue. My first sensor failed to scan a couple of times after I unplugged it from the computer. It told me to try again in 10 minutes. I tried 10 minutes later and it was fine. I am more careful to quiesce the scanner now before removing it from the computer. It is a USB device after all. So, if it hasn't recovered after 10 minutes it's probably dead. To those unsure about buying this system, it certainly has pros and cons. I love the fact that I can see the pattern of my BG over a period of time - it makes a huge difference to understanding how your body is affected by food and insulin, but more than anything, just what is happening in between those events - this is an insight you could never get from a BG meter.
