Summary: When i try to use a disguise on my server i get the error message "That disguise type was not recognized" I use the /d command followed by a mob and it doesn't work (ex: /d creeper)  I have added subtypes but they don't make a difference. I can disguise as players but i would like to disguise as mobs.

DisguiseCraft version:
v#5.#0

CraftBukkit version:
CB-1.#6.#4-R#.1#0

Additional information:

I get "That disguise type was not recognized" too when I try to disguise as a mob on MCPC 1.6.4.

I get the same thing on latest tekkit build. I can disguise as a block or player and subtypes show, but no mobs are accessible. Running on 1.5.2

Likewise, I am unable to get DisguiseCraft to recognize most of the vanilla mobs. Running 1.6.4 MCPC-Forge server w mods and plugins. Have reviewed all configs over and over. Not sure why not able to use all mob types. ANYONE FOUND SOLUTION OR HAVE SUGGESTION? Why wouldn't vanilla mobs be detectable by DisguiseCraft??
