LG TinyMCE extension not working

Greetings,

I have installed LG TinyMCE (v.1.3.2) into EE (v.1.6.4) with TinyMCE (v.3.2), following these instructions. When I then try and add or edit a custom field there is no option for “LG TinyMCE” as a field type. Previous to this, I attempted to install an older version that applied the settings to text areas, and that didn’t work either.

Thanks for any assistance!
