If it still wont race then you may need to go into the race properties and chang ethe time. i think the default time for a race is 4 minutes but im not sure. i do know that you MUST get the new patch to race online the stock game wont work online it had some bugs or somthing. and you also CANT record unless you have the patch.
even the slowest dial up modem runs great online racing, some how they have managed to only send the video data of the car (wich is VERY small) and this doesnt require much comunication threw the modem. i played a guy from a different country (That RealRace Per guy from europe) and it wasnt a bad race its alot like racing a recorded race in my opinion.
i think that when you start adding a track editor problems will start with online racing. but i think they should design different ones that we can DL or run the tracks backwards or somthing.
i would still say this is the best R/C racing simm ive seen so far. if you have a geforce video card you can CRANK the resolution and then the video really looks good.
