using cygwin, I also renamed any files with *.*loc in the extention removing just the "loc" part of the file extention in the directory
C:\Program Files\Adobe\Adobe Encore CS6\Library\* and its subdirectories.
So files like .psdloc became .psd
and .emloc became .em
and .m2vloc became .m2v
I repeated the process for the directory
C:\Program Files\Adobe\Adobe Encore CS6\Styles\*
The I restarted Encore and the Menues and styles sprong back into like.

Advise to anyone wanting to try, You don't really need to use Cygwin, it was just quicker for me to script. Also, suggest you BACK UP those directories first before trying thesame.
