It has been over six weeks since Cakewalk has corresponded with me on this issue. In the mean time, Cakewalk has chosen not to respond to three requests that I have emailed them for an update on this issue.
It has been over four months since I have exhausted advice on this forum and entered the technical support case on this issue.
In summary, Cakewalk has ceased responding both to my forum posts here, and to my technical support requests and has offered no explanation. All of my correspondence has been professional and civil in tone.
After using Cakewalk products successfully for 34 years, I am suddenly beset with the worst support that I recall ever having had for any product (with the possible exception of the period of silence when Apple was buying Camel Audio). In addition, in the absence of any explanation or information, one tends to assume the worst reasons for why support no longer exists. I doubt that I am alone, so I therefore feel that it is in Cakewalk's best interest to inform us of the reason for the apparent cessation or extended delay for technical support. The actual reason has to be better than no response at all.
