Vectrosity Error Loadlevel

When i use LoadLevel the vectrosity shows this stack error:

Vector object not set up
UnityEngine.Debug:LogError(Object)
Vectrosity.VectorLine:LogError(String)
Vectrosity.VectorLine:get_vectorObject()
LineManager:LateUpdate()

Does anyone know why?

No, but a random guess would be that LineManagers game object is kept alive with DontDestroyOnLoad and is referencing an object from the previous level.
