you could try a complete data logger reset
(this has worked for others)
exit WD
i.e a power down of the console (that means removing batteries too)
then remove the data logger for 5 minutes
before putting that back
then power up the console
then use say weatherlink to set the time and date on the console and set the data logger to 1 minute logging interval (or use WD to do that)
then it should behave better for the next restart of WD
