Im being Mr Pessimist here. Are you sure the software for 200 pounds is the real thing? With the pound in the Keller at this moment maybe you should think about buying the latest version from somewhere like Forever https://www.forever-ots.com/ or Printequipment https://www.printequipment.de/index.php?lang=1& s in Germany. 399€ is 360 pounds.
And then you can use their product support help lines.
