Help Needed about basic tutorial - part8 - Instantiate Player

Hello,

i followed the whole basic tutorial and now when i test it , i have no player instantiated into rooms, and i have no error message..
i have updated some Alerts with deprecated code, it seems to be ok,
but there is nothing than can give me a clue about this non-spawning issue...

i have tested with the Demo scene, and it spawn the character but it's not followed by the camera,
i have checked both scripts to compare any error possibilities, but fund nothing noticable,
i have no idea know where i have to look to debug it.
