I've just had a dreadful start with Presonus. After aquiring a Quantum HD 8 and a faderport 16, I only just managed to register the Faderport. I cannot register the QHD nor can I activate the Studio One Pro which comes with the Faderport. Even though my PC 'sees' the connected QHD it refuses to accept the registration. Which probably doesn't matter as I can't activate the software. This is so low...cheers,
