You're welcome, i'm glad you were able to solve your issue!
Just drop it inside your Plugins folder, it should work just fine. You might also want to update your Spigot Jar as you're running other version than mine. (https://mcadmin.net/)
As you're using Spigot, have you tried this version? http://ci.dmulloy2.net/job/ProtocolLib/293/
UPDATE: Confirmed it works on a fresh installation of Spigot 1.10.2
