Just looked. They are moving servers this month, so it might be eorth trying again in December. Just seen the stack of servers they have bought, impressive.
EDIT: Another option would be to pay for hosting with someone like Bluehost.com, where you get unlimited storage and transfer bandwidth. I think you can get a deal with them for 50% off as well, so it would be $2.50 for a months hosting. They would provide you with a domain name, some easy setup tools for a Wordpress or Drupal site, and you could also add a few non intrusive ads to make your money back.
EDIT2: I see you have already used Mega to share a file, could you not do the same for all future files? I've had good speeds from Mega downloads in the past.
Another thought would be BitTorrent Sync, but I think you would have to host the files on a PC or a VPS online.
