i have a used MK1 in really great shape. it was at garage sale so no previous owner found. i have original CD with Serial # on case. i installed the original MK1 software and unit is working but only in Demo mode. i cannot activate because it's already registered. Can't get in touch with previous owner and NI support is only "CHAT" and doesn't offer much help. I end up downloading MK2 software and it does work but it still only works in demo mode and ask me to activate. Is there any way i can get this resolved so i can have full access to the software? or am i stuck
