They did not 'mess it up'.. previous Python version reached end of life and the owner had to make the difficult decision to upgrade to the new Python 3, which made all scripts that were not in program obsolete.

I have had several vendor made scripts I paid hard cash for become unusable in P12 (just like it happened at a previous time betweem P8 and P12 somewhere I think), but several of the free ones were updated by either their owner or others who took up their work. Software changes, evolves and we must adapt. There are things I would wish Bondware would have done differently,  but this was inevitable and actually overdue.
