Been There! If you open VWS, go to 'Settings" . In the drop down menu, click on "Recall Daily, Monthly, and Yearly Archive'. A box will come up with bin files for years (i.e. 2014.bin) . Double clicking on the Day, Month or Year that the error occurred will bring up a box that you can modify the values. That will correct it...for the most part. This only happened to me once, last year, and I think I had to go to one more area. I will look through the program now, but that is where I started. Let me know how you make out!
