un/registering events

[EyesMcFly]

I have a disable/enable command in my mod.

I have set it up so that when you enable it,
the necessary events are registered.

And when you disable it the events are unregisterd.

The problem is this isn't working.

The events are not actually registering or unregistering.

Is it impossible to 'hot' register/unregister events like this?
