Sorry for the long answer, this is code:

#pragma strict

function OnTriggerEnter(col : Collider)
{

   if(col.tag == "Player")
   {
   
    Application.LoadLevel("Level02");
    
   }
}

I don’t see anything wrong you’re doing there, I wonder if something is causing problems when it gets loaded in. Maybe try making it so when you finish level 2 it goes to level 1 to see if the same thing happens.
