Hi, I am trying to join an online race, but I get the message saying "Your computer is not at the server hour. Do you want to change the hour?" I click yes then a message saying "Server date and hour : 17/07/2011 23:22:05 [GMT +1] To set your computer with the original date and hour : 18/07/2011 00:22:05 [GMT +2]?" I click yes then get the message "The date and hour were NOT able to be updated! Please adjust the hour manually." How do I adust the settings manually? Thanks.
