After upgrading to Braintree, most of the pro-channel plugin icons are gone. The only ones still visible are Bark of Dog, Tube Saturation, and Fx Chain. Additionally, in projects created before I upgraded, the Console Emulator (Bus) display is blank (no controls or meter, etc). Removing the plugin and then re-adding it to the seems to fix the problem with the blank display. Did the GUIDs change or something?
I don't have a lot of projects that use the pro-channel plugins and everything still seems to work fine, it just looks a little broken.
 

I believe those experiencing this issue found a VST reset fixed it

Thanks.
I did a VST reset and it did indeed fix it, but now melodyne is crashing during the VST scan and no longer shows up in the region fx menu.

If the scanner is shutting down, move the offending plug-ins out of the scan path temporarily until a scan can complete.Then add the plug-ins back and rerun a normal scan or let auto scan pick them up.
 
If there is Load Error message while scanning there should be options to Disable/Enable the plug-in. If I know the plug-in was operational before the scan, I enable the plug-in. It is also possible to to disable the plug-in then manually run a scan for failed plug-ins. The failed plug-in scan option is enabled by a checkbox above the red circle in the image above.

Got it sorted. I moved the license to my iLok, uninstalled melodyne, then reinstalled it. It looks like it's working fine now.
Thanks.
