Even with Register 1.5, I get spammed with these errors. The plugin works, but my log is unreadable.

Thanks, Zombie. I've just released a new version of the plugin that uses Vault instead of Register, and that is up to date with Bukkit's release APIs. I'm sorry this has taken so long, but I hope you'll continue to enjoy the plugin. :)
