Ok, this is the file you need to add. (I missed this the first time).
When you're adding the CEP Hak's to your module, you add the haks in the little hak window. UNDERNEATH that there is the custom tlk table. You need to add the file cep.tlk in that window... I think that's the file name. It's something .tlk. This file is what tells the toolset how to categorize the CEP items/scripts on the palette.
This is the #1 btk* error encountered with CEP.
This image should help, notice the field at the bottom.
*btk = behind the keyboard =)
