Please in future for all error reporting, not just for myself but to any plugin developer, please upload console outputs or logs to either pastebin or hastebin. It is annoying trying to read in the format the forums posts it in as it's just a wall of text. As for the error, I have just fixed this in the latest version I have released. If you still encounter issues please delete the config.yml for the plugin and it will generate correcttly now. Sorry for that problem and thanks for reporting my oversight so quickly!
