Logging History WRM200 Issues

Over the last few months and intermittently WD does not pick up the history from the WRM200. So normally when I fire up the PC I click on WD and the program starts with no weather info showing within its window while the history file from WRM200 uploads. Once all history uploaded WD then catches up and behaves as it should. However now when I fire up the PC WD starts up and the log files upload but WD displays weather data immediately and shows no data from the logger and all the logging data is lost. I have confirmed that by looking at the log file. I am using ver 10.37S81 which I downloaded in an attempt to fix this issue. Hope this makes sense. The attached screen shots show the 3 lots of lost data at 10pm, again from 12am to approx 9:30am and again from 12pm to 9 pm. Any ideas? Andy

All sorted by going back to a restore point I created at the beginning of Sept. (Windows 10)
