Hey there! To confirm, are you using the latest version of our plugin version 2.0.3?

Make sure you have the latest version installed, then in your server console run the command: tebex.debug on

After that, try to re-send the package. You can force the plugin to check immediately for packages instead of waiting using tebex.forcecheck. 

If you still run into the same problems, please post any errors that appear in your console.
