Seems to be a bug when trying to teleport to a player with a forcefield running. Had this problem with one of my admins. Only fix I know is to remove your player file so you spawn at the world spawn point.
I have removed your player file so you should have no problem logging in. You will loose whatever items you had on you at the time.
If you need some help remaking items I can help with that next time I see you on.
