Tmodloader bug I don't know where to put this

I'm having a bug with tmodloader, when I pressed singleplayer the character I was using changed to the default male, 0 mana and 100 life (I have used a life crystal and a few mana stars) and it doesn't show a name. I can't press the play button with the character either

I turned it off and back on again and it's still happening

I made another character and my world also has no name and says "Unknown World"

I pressed play on the world and now it's showing this
