Ok if your willing to try again, contact Darren or Howard at ketron UK, they are very good, and tell them your experience with Thomann, but I put you in touch,Darren stayed with me all night by text till we got it sorted, fair play super service, I'm not saying anything against AJ, he has also advised me and answered my Messenger, and wow! his demos and singing is excellent, I watch all his videos, AJ is also right about the faulty pen drives, it's just a chance you take and could get lucky, I'll be in touch
