What are these? Please list these problematic files and I'll take a look.
They are dotx files, used to create new files when accessed via File=>New=>Sample Templates. Only a few work. All of the origin*, urban*, and median* templates throw up the error message, whether using them to create a new file or trying to open them directly.
I can see this, and it looks like another bug, not so obvious yet. Please open another report for it.
