I am so annoyed at myself. I really wanted to dig into my kids numbers tonight. I have not done it in a while, but in the last week or two it seems like there have been changes. We are correcting alot. Lots of temp baslas (130%, 150%) so basals are leaping up. I am on defense, not offense, and tonight I was going to go on offense. i was getting my d-dad attitude in gear and i was going to wage war against Mr T1D, that interloper. So I fire up Dexcom studio. Plug in the receiver. "no receiver attached" hmmmmm Change the cable. Same thing Click on: Tools->Drivers for Dexcom receivers->Install driver for All other Dexcom Receivers It recognizes the receiver! Woohoo! I start looking at the reports and there is NO DATA after 10/1/2015. I check the receiver and the receiver thinks it is 12/30/2014, not 12/30/2015. So I use Dexcom Studio and slide back to 12/30/2014 and sure enough there is INTERMITTENT data between 10/1/2014 and 12/30/2014. What a mess. So basically I have a completely wrecked file. So I am annoyed and I click on Tools->Reset Receiver Database i get a warning that it will reset the database. I click ok. The receiver reboots! Upon turning itself on I notice that it requires that I do a sensor start! So for my effort: - I don't have the trends I need, - I have lost like a years worth of data, - and the coup de grace My kid has to poke his finger twice again in a couple of hours grrrrrr.
