Hey,
Thanks for the input, but to be honest I've deleted the file and gone with a torrent program instead - its Linux Yellow Dog 5, so its cool.
Oh and yea I tried to restart the download but as far as I could make out, the program believed the file had been downloaded fully - unfortunately not the case though!
Just for interest it was a swiss ftp -
ftp://mirror.switch.ch/mirror/yellowdog/ which was giving nice speed 250-300kps, but cut me off twice!
So now stuck with speeds of 15kps and using up twice as much quota!
Ah well!
