Hi Thomas,

You are correct in that the software and its packages are close-sourced. I have emailed the provider but their technical support staff has stated that they have exhausted of all ideas. 

An interesting thing to note is that this part of the code has been previously used by another individual with success, on the same computer.

Kind regards,

Natalie
