Ok finally got a chance to go thru all the mess of building a pawn anyways the problem is simple. Most likely you are trying to spawn the player inside something either the ground or an object. For me using the example map I had to change the MakeTransForm Z to 200 instead of 30. 30 was in the floor so it would not spawn once I made it 200 it worked fine.
Let me know if this works for you also it will not work until you kill your pawn which I can help you set up also if you need.
