Development Assistance LibsDisguise InvalidPluginException: java.lang.NoClassDefFoundError:

Getting this error in console, and the plugin does not enable.
I've added both Protocol lib and libs disguise to the build path, and both are present as plugins on the server. Thanks in advance, and sorry if this is a noob mistake.

Code:

You only need Libs Disguise in the Build Path, but ProtocolLib and Libs Disguises in the server. Are you sure you're running the latest versions?
