Orebfuscator plugin not working for 1.7.10...

I have been trying to install this plugin to my server and it seems to work as intended when I first start the server. However, if I then go to close the server and restart it I get this message:

Any help would be greatly appreciated!

The plugin has a invalid plugin.yml. Are you sure you are using the newest version of that plugin?

 

It is the newest plugin version for the minecraft version I am trying to play on, yes. I am just wondering why does it say invalid plugin.yml after the second time I load my server because it works completely fine on the first boot of my server, then after that it never works, I have to keep deleting it and dragging the original copy back in.
