    maybe it helps to unplug USB, power-cycle the ProfiLux
    if not - change the COM-Nr in the device manager (and in ProfiLuxControl accordingly)

    that worked, thanks ... now for firmware upgrade...

    i usually do the same but just wanted to try otrher ways first and get things running properly again as i have recently had an emergency situation with an overdose due to a sticking button, i will do the firmware upgrades and then look at bios, thanks again for your help on this
