urgent help needed - Live update taking too long (days) on dial up

can anyone tell me if there is a way of getting live update done quicker as i am on dial up and can only go on the internet for four hours at a time. i have been trying to get it to work for at least four days with some of the time going online 3 times in a row. there was 113mb to update and it still is around 94mb even though it says it is downloading
