Hi thanks for the tip, I tried this and replaced the dll, unfortunately unsuccessfully. When starting, Fiesta shows a small alert window “Out of range” with an OK button. When clicking OK Fiesta hangs. Second try same thing except Fiesta crashes. Third try same thing again but Fiesta finally opens, but is extremely slow. It seems to recognise the Riya controller, but there is no output to the laser. The LCD in the controller does not draw the selected Fiesta pattern. Any clues?
The dll size is 474 112 bytes.
