Yes Dave - this is the very issue Sofy and I have been working through.
After doing a clean removal and re-install, CineRender is still not launching. I'm not sure what is happening. Maybe I need to re-download the install DMG file?
In addition to my previous VW issue that I was having with a corrupted preference file - I'm beginning to think that simply removing the plist files, application support folders, and deleting the application still leaves something behind.
I'm not sure what to do to trick my computer into thinking that Vectorworks has never been installed - because there is something that seems to remember.
