    @AquamenEithber
    There can be only one instance that extends Javaplugin. Make sure there are no other classes extending Java plugin and that you are not creating a new instance of Inicio.

    @Aquamen I think you instance Main.class in an other class. Please check in your class Comandos if you have an instance of Main (like new Main() or something like that).
    The Main class which entends from JavaPlugin can be instanced only one time and it bukkit who do that.
    If you need more help please post your Comandos class code.

    On disable, you aren't saving your config so on enable it might not recognize the config as it hasn't been saved on disable. Try take the RegisterCommands(); out of the if statement in onEnable and just put it at the top or bottom. Just an idea :)

    @Aquamen

    Just put out your RegisterCommands() method of the if statement.

    Explanations :
    Your condition in the if statement is true only if the config file not exist, so at the first start the condition result true so it work but at the other start the condition result is false so the RegisterCommands () method isn't call.

    PS: rename your RegisterCommands() method by registerCommands(), in convention method start with a lowercase.
