No you're not alone.
 
It feels like some fighter pilots may have some time off as all we got this month was a new way to add a track which rookies can do, where in the previous month "Oh boy Melodyne 4 is here!" from the marketing brass.
Or, they're hunkered down playing Melodyne 4 catch-up and our cries for deliverance are heard after all.
 
There is no doubt that something is amiss with Melo4.

I finally got the Melodyne Trial activated on my machine, and although I have not tested it too deeply as of yet, I have not gotten it to crash either (Melodyne 4.0.2.003 on SONAR Manchester). Just FYI, there is a 4.0.2.003 version of Melodyne out, so is worth updating Melodyne if on a previous version (I noticed the error log above showed an earlier version).

I always bounce my MD edits asap at least.

I updated to latest version, no more crashing here .

Are we in MeloCrash land to understand that you too were one of us before you updated?
And either way, can you tell us all down here in the pit what version you updated to?
 
Thank you.

+1, I was just playing with the trial, and there is a 4.0.4.001 build available. Definitely keep up with checking on updates as the version is new. I had the trial installation hiccup, and that error took two patches to rectify, so I am 6 weeks behind the power curve here.

The email request to Celemony is the best route to go. It may take a couple or three days to hear back until you get on their "squeaky wheel" radar.
 
My personal issue was my activation went through, but my computer crashed so the demo (client) never went active. Although Celemony initially said they had no record of an activation, the email reminders of "demo time running out" made me reopen this. Until the 4.0.2.003 update the activation page (online) actually removed the demo entry for this situation; but suddenly it was view able again and gave a popup of "already activated."
 
The solution was they simply needed to reset my entry in their server. What made me most irate is that it is my understanding that an internet connection is required to use Melodyne 4 (sans ILok) anyway. I am always connected, only on one machine, yet their "phone home" feature doesn't check the client side's functionality - only that their server has your computer ID on file.
 
Perhaps my standards are based on the higher end gaming community... During a program start they patch/repair the client when necessary in addition to the "server handshake." I am not sure I have come across anything DAW-related yet that pops up "Hey, your installation is FUBAR, want us to fix it for you?" In my particular case it could have been as simple as "Oh, your computer shows the demo active... here let me activate that for you." Perhaps too simple of a concept... but I happen to like simple.

UPDATE - The 32-bit version is working; the 64-bit version fails. So what I did was to uninstall everything and reinstall ONLY the 32-bit plugin. So that's how I solved it.

i tried installing Melodyne 4.0.4 2 weeks ago on my backup rig & it caused massive errors & could not be scanned by the VST scanner.  i immediately contacted Celemony support & have still not heard back from them (with the exception of a tweet apologizing for the delay).

I asked about earlier versions and Celemony confirmed that the upgrade 1) requires relinquishing a previous version and 2) an internet connection (or iLok) is required. The only recourse you would have is to contact them directly.
 
I have not experienced the SONAR crash with the trial (yet) but not used it extensively either.
 
Although not elegant, an option for you is to try Melodyne in stand-alone mode.

I had forgotten or not known that there was a standalone version. THANKS! A pain in the a$$ but better than not finishing my CD in time.

In my workflow, I create a clone of whatever track I want to perform "surgery" on (e.g., gain leveling, reversing, MD edits, etc.).
I can then archive the original.  I always have that as a fallback if I find later that I have an artifact from the edit(s) I made.
Sometimes I'll see these artifacts more once I've compressed, EQ or saturated the track or in the context of a more final mix..  I then have the option of going back and starting over with the original track.
 
(Warren Huart made a similar recommendation in one of Produce Like a Pro Academy videos (https://www.producelikeapro.com/).  So I'm in good company LOL.)

I can confirm some crashing with Melodyne 4 Studio.  Especially if you clone an audio track with an instance of Melodyne in it.  I've also had some frightening distortion type issues at the beginning of an audio track with Melodyne.  I've seen the level meters go to +84!  It's a very LOUD click!  Didn't think anything could go past zero but it's happened.  So, yes there are some stability issues it seems with Melodyne 4.  But what's bummed me out is these guys didn't pay attention to improving the audio quality of polyphonic processing.  It still sounds "phase-shifty" on most things.  Also the splitting of clips...  mother of gawd...  software should be smart but...  I don't know if I'll ever use the sound designer and...  I'm OT now.... 

Weird...    Melodyne 64bit has been working great for me, no crashes at all.  I updated to the 4.04 build about a week ago, but even that seems to be OK based on limited testing.   I am still on Win7 though...

Celemony must be really backed up with tech support for this new release.  going on 3 weeks now

I remember the Essential upgrade from 2 to 4 explicitly warned me that if I do this there is no going back. As usual I thought "Pfft, what could go wrong..........."
