Error: A problem occurred while writing the output CSV files.

When trying to convert ANY of my Garmin Edge .FIT files using ANY FitSDKRelease_ , I now get an error message. Currently using FitSDKRelease_21.171.00. Garmin Connect reads the file fine so there is no issue with the file. I place the file on /java/FitToCSV.bat and I get

"Error: A problem occurred while writing the output CSV files."

This used to work fine in the past, How do I get this to work again?????
