Hi Daniel,
please ensure that you are using the most recent SiDiary version! Actually there was a change in the driver several months ago, when Abbott had release the "Lite" meter series because these meter have a larger memory.
So from that point an update might help to resolve this issue.
If it does not help, please try the button "Test import" from the settings tab within the Freestyle driver screen. This will open a log file including every single value which has been processed by the driver.
If this doesn't help to dig something out, please drop us a line at SINOVO support so that we can activate a setting in your installation to get a pure dump of everything the meter sends during the communication...
Hope this helps!
