You are using VoxelUpdate, which is currently discontinued.
Download the latest version from jenkins and look for the installation instructions in the documentation here.

In his defense, voxel update is the plugin you download from bukkit dev

The last VoxelUpdate jar file was uploaded to VoxelSniper's dbo page on Aug 30, 2012...

So we should probably update bukkit dev yhen

Does @neutronrocks have a github account?

Well we should either

A) Fix VoxelUpdate.
B) Stop worrying abouy curse "own" the plugin.

FYI we already chose B
