When the connection fails
If it occours during a race, approximately every 3 minutes, don't worry, you will finish it easily.
Even if your connection usually works properly, you should keep in mind a few things: once the race is over and you're back to the utility section, don't forget to check if your timing has been ranked, especially in the overall ranking, thus making sure that not only has it been uploaded on the server but also added to your overall timing. You can do this by clicking on Upload Time, which is to the right of the ranking. If after clicking on Upload Time the ranking page does show, your connection is back.
If it doesn't, you can minimize the utility section and take care of the problem, we're sure you know how to deal with your internet connection when it fails.
At this point you can go back to the utility section and click again on Upload Time and then Refresh, if both the clicks make the ranking page load then, and only then, you can start the next special stage.
You should pay attention to this procedure especially during the service park. It's important to verify that, once you clicked on check time, the ranking page loads and shows your time on the left column but ESPECIALLY on the right one. To make sure this happens you should click several times on Upload Time and Resfresh. Once you're sure that the server has received and elaborated your “Stamp” at the service park then, and only then, you can start the next special stage.
The only thing you mustn't do is going on with the race without making sure that the server has received and ranked in the overall ranking your previous timing.
