Hello, i realllly reallly need some help, my laptop has jsut died and its got a huge essay on it that i have to hand in tomorrow that count for a big part of my degree.... :s no the up to date version wasnt saved elsewhere

as i pretty much rewrote it in a few hours, and was going to save it then it crashed...
basically when u turn the computer on it bring up the start up screen then stays blank then comes up with a message saying windows file /windows/setup32/config/setup is corrupt or missing, press r to repair using first screen and windows setup cd.. but u cant do anything with it bar turn it off and going onto setup doesnt do anything...
im desperate here, please help if u can or know anywhere open on a sunday

thank you very much
