I can't edit or even load any QML files in Momentics, get the error message;

"Could not open the editor: The editor class could not be instantiated. This usually indicates a missing no-arg constructor or that the editor's class name was mistyped in plugin.xml."

Source files are fine.

Log shows...

Re-install seems to have fixed it.

Had the same problem where I insalled beta 3 over beta 2 (into the same directory). 

I uninstalled Beta 2 in "Remove Programs" and then manually cleaned the install directory and reinstalled Beta 3.
