Emanuele, are you trying to run this game on a 32Bit Windows?
As Yunus said once: The races cannot be viewed on 32-bit computers because there are not enough hardware resources to do so.
Please, try another platform.
Getting the same issues with my race that was to start at 7pm. Can sometimes get the race viewer to load but get the message saying "race has finished"
Webpage seems to be running very slow.
This has happened to me on Safari browser on wireless connection.
This has also happened on the iOS App using Wifi and also mobile data connections.
