Ensure that you\'ve run the updater in recovery mode (avaiable on the planeshift menu group) so you have the last version of the game avaiable.
That said, if you crash with that same cause everytime you try to launch the game, it would be nice that you detail which steps you took (perhaps maybe including the char past choices) since that message denotes that a float has been tried to be divided by cero, which caused the crash. Most commonly that\'s due a variable that has no right value when the function that makes the division is called, so perhaps if that\'s a recurrent error for you, providing the steps you followed could help the devs to track that problem down.
