enchantment plus plugin couldnt be loaded no matter what version of it

so i wanted to add enchantments plus plugin to my server with my friends, but i keep getting this error: The plugin 'enchantments-plus-3.1.6' could not be loaded. (i tried version 4.03, 4.02 and 3.1.6) Why is this happening? only other plugins are Simplehomes and Simpletpa
