Melodyne Crashes - how I envy you other guys who say it works fine...

Here's a screenshot of Melodyne tangled up in Sonar X1 again.
New DAW, specialist supplier, top of the range spec. incl. 16GB of memory, Sonar X1 expanded and Melodyne Editor 1.3, all running 64 bit.
 
How I long for the old Melodyne Plugin (now discontinued) which worked faultlessly for years.  How I also long for a software company (Celemony) to take its responsibilties seriously - taking my £112 to move to Editor and not bothering to seriously examine the possible causes of their product crashing and taking Sonar with it.  They won't examine CW crash dumps (even though one is in text).  I'm pinning my hopes on the crash reports I sent to CW for which I've had an email saying they are under review.

I feel like a Caveman, because I never exercised my free upgrade from Plug in to Editor... but I've yet to hear anything that gave me the confidence to retire the app that works.

Celemony could at least allow us to run both.

I have imagined that I will someday just buy a second license so that I can keep Plugin alive while I finally learn the quirks of editor.

Not much left to say.

I've tried every conceivable alternative setting in Preferences that I thougbt could make a difference.  Today I tried disabling my Firewire ports, then using WDM drivers in Sonar instead of ASIO....the lot.

My last DAW ran the old Plugin fine under XP, then I reformatted it to move up to Windows 7 64 bit and I've had this problem ever since.

What was really galling was to spend a lot of money after that on a brand new audio-only PC (spec below), and to find the same issue.  When I got the new PC I tried an experiment and installed nothing at all except Sonar and Melodyne.  No MS Office, Explorer, printer, zilch.  And what do you know - the same problem.   Five minutes or so of working with Editor plugin and then freeze, and Sonar crash.  The Sonar crash is always so bad I have to cold boot the machine every time it happens.

I've invested in Studio 1 Pro Ver 2 solely to port across a rough mix backing track along with the lead vocal track just to be able to work in a 100% stable environment, porting the bounced Melodyned vocal track back to Sonar afterwards.  I found I can also do this with Reaper.

And with both of those I don't even have to change the samples from 128 (Melodyne recommend going to 1024 to use Editor in Sonar.......but that doesn't help anyway).

Melodyne Standalone works fine, but I need a backing track to be able to edit/correct a vocal track in context.
