Seems to be a very good plugin, but when I try to setup the plugin...

21:26:14 [ERROR] [BackpackSystem - MySQL] Connection failed!
Error Message:Communications link failure
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
>
21:26:14 [WARN ] [BackpackSystem] No MySQL-Server connection. Please check the file "config.yml"

I already setup MySQL in the config file and also I setup DbLib and configure MySQL there too but I don't actually get any changes.
