Hi, i'm hosting a 24/7 bukkit server for me and some of my buds, and i ran into a problem when I tried to use Movecraft. When I right-clicked on on the sign with a stick that would make the ship, it didn't do anything, and outputted the stuff in the attached image into the server console. Now i know i'm supposed to post the server log also, but when I look in it, none of that stuff shows up. Does anyone know why it doesn't work, or where that would've been outputted to? The server's running windows xp, and it's the latest bukkit 1.7.2 build. No mods, and the plugins are in the other attached image. Sorry if I am overlooking something obvious, I know how to set up bukkit and stuff, but this is just over my head. Thanks to you all!
A very similar error comes up when I try to do /bc or /broadcast in-game, via command block, or via the console.
