void Start()

{

    vp_Timer.In(0.0f, delegate()

    {

        Debug.Log("Start");

    }, 10, 1.0f);

}

Version Timer can't work when you call it Start() .
You can change the delay to 0.1f  then can fix it.

The Reason is Easy. When you call it at Start,the information of Event is like that:

So ,When you Execute the callback,it will br recycle.
