Hello i hit the same issue. The problem it appears because they use os.rename to save information in file, about what is the latest collected data, but in Windows this fails after the first collection. It fails because in windows os.rename can’t save the file if the destination exist.
You can check the Python Docs : https://docs.python.org/2/library/os.html
For a workaround i changed the Python script to check if file exist before the rename and if it's existing, the script delete it.
