Paragon NTFS-HFS Converter Bombs Out after prep

Hi, I am trying to use this converter programme to migrate an HFS+ disk to NTFS but it appears to fail after 20 minutes or so repeatedly with a component failure.

The event viewer information is poor and no other logs appear to be stored giving more clues as to why.:

Code:

This is on a windows 8.1 machine, with a Lacie d2 quadra hard drive connected via usb.

Appreciate any help in finding a solution before I need to go the long way round.

Many thanks.
