Not sure why some people are having trouble getting a response from Cakewalk support, but I can report that my own recent contact with Cakewalk support, on 09/19/16, was answered and resolved rather quickly by Cakewalks support staff. Luckily, my issue, which had to do with the greyed out "Insert Synth" button, was addressed in the next patch. It did however, take a few emails back and forth, to get to point of the problem. All of which were responded to in a timely manner.
Just a thought, but maybe the new monthly update model, has put a temporary strain on the number of Cakewalks support staff, available to respond to emails and phone support. It's probably easy for Cakewalk to hire someone to reply to support emails, and take phone calls, but they still need to go to the "code gurus" to get the actual answers to the problems. Those guys are all busy on getting the next update out, which may be the reason for the slower response times. If this is the case, then support should only get better, as more support staff learn the ropes at Cakewalk.
