I suspect that server capacity is throttling download speeds. My initial attempt lasted over 14 hours at 40KBps max, and failed during the final MBs. My second attempt lasted a bit over 10 hours and after reaching speeds up to 70KBps gradually dropped to 40+KBps. So if things slow down too much, you could try again and hope for a better throughput.
PS, $1.68 is a modest fee, but even without it you would have had until Jan. 14 to complete your download.
