You didn't say when it was you first contacted them, so I can only assume it was relatively recently. With that in mind...
It can take a while to hear back from them, weeks, in fact. I don't know if this is because of workload or a shortage of staff, but by the time I heard back from them, I'd actually forgotten I'd sent a request for support.
Bottom line: gotta be patient.
Or email one of the Cakewalk guys via this forum. (I don't know how that'll be received, so if you get into hot water, you're on your own. ;) )
