yep I did, to no avail.
But I had some trouble getting commands to the Tricklestar, and in fact the tricklestar was not automatically recognized in any way. I put in the MCV stick after a reset, and this USB interface did get recognized.
I could then transfer the Merten config, and everything works now (fingers crossed).
What is wrong with the Tricklestar, I could not say. I will try to reset it some more times. If it does not work, we have perhaps a problem in the USB stick!
