TinyMCE Will NOT Work

I’ve followed the TinyMCE and LG TinyMCE Custom Field instructions to a “T” and am not seeing the editor show up in the field I’ve assigned. I get the WYSIWYG drop-down in my custom fields editor and the correct path to the TinyMCE js shows up when I view source on the relevant publish page. I’m flummoxed at this point as I’ve gone through the instructions multiple times trying to find a flaw in the install to the point of duplicating the install twice to no avail.

Anyone out there have any thoughts or suggestions?

Links to the JS files as shown in the source code of a publish page (leading and trailing brackets removed so it will show up).
