So the plugin wont even load for me... I'm running it on Craftbukkit, the latest dev build. Both v2.7 & 2.7.1 dont load. It says enabling, and it enables fine, then at the end of Minecraft Server loading, it unloads it. I've tried running it with all my plugins, and by itself with just Vault. I use /plugins in-game and it says its there, but its red, so its not loaded/active. Vault is working fine.

Check your server.log. It contains useful information about problems occuring.

Oops... jst double checked my config, there was an issue which the old version obviously didn't pick up. Cheers! All is working now. :)

Great!
