Dirac Dimensions FIR configurator

Hi!

I am using the Dirac Dimensions add-in, and I want to create my own FIR filter. There is a tool in the add-in that runs on Python, however I have followed all the steps in the PDF but when I run the command I don't get anything... It just moves to the next line and there are no files created. I am trying to create the smallest FIR config possible.
