Eu também sofro desse mesmo problema. A corrida congela em 3% de carregamento, mas consigo treinar.
This is a different issue. If you are using the web version please clear all cached files - it could be cached JavaScript from the old version before the update. If the problem is in the app, please ensure you have updated to the latest version. If the problem persists after this please email support@igpgames.com where we can provide detailed support.
P.S. Please write in English in the main forums - otherwise they become a mix of languages which nobody can read.
