Hi Bill,
you are correct that the sample extension should work as is without any changes in Photoshop CC 2014. The name of the sub-folder that contains the extension files and folders also does not matter.
You can enable an Error Logging mechanism for extensions by activating a check-box in the Preferences dialog of the FileInfo dialog. Please activate it and restart Photoshop. You will then see a new control under the panel list that opens the error reporting dialog. Please let me know if there are any errors reported.
Regards
Jörg
