Hi, and sorry for your problem!
What version of Bome MIDI Translator Pro are you running? If not 1.9.2, then please upgrade. You can find a new download at bome.com by logging in, clicking the person icon and then going to the products menu.
If you are already running 1.9.2, please delete the settings file as well as backup settings files (or store them somewhere else). Then restart Bome MIDI Translator Pro . Typically this problem occurs if you have some placed Bome MIDI Translator Pro offscreen and then restarted as the settings file keeps the last screen location and restores to that location when started.
See this post to find the settings file.
