What do you do to obtain this crash?
What version are you using? Steam or non-Steam?
Steam and also this crash is obtained when I start any race APART from the tutorial which runs fine.
I think I fixed it... I had to create a new Ragdoll Runners Profile and it worked with that but as soon as Ichanged it to my normal account it crashed again.
Oh strange... Do you have special characters in your username?
