Zworld's PK22XX controller

Hi Folks

I have a Zworld's PK22xx controller  which is lacking software. I remember that the software for this controller consisted of a single 1.44mb floppy diskette which was called EasyStart C.Unfortunately, I lost this diskette and I am unable to get a replacement from Zworld as all my e-mails to them have remained answered.I programmed this controller for running a multiple stage compressor along with permanent magnets , Hall effect sensors, pressure transducers etc..The controller worked remarkably well in a harsh environment.fkawlessly.

I would highly appreciate if somebody could help me get a replacement diskette.My only regret is that I should have made mutiple copies  of the diskette  while it was in my possession.This controller appears to be in high demand as it is selling for about $890  on eBay minus the software
