It does appear that the server jggimi uses is down at the moment, you can either wait until it's operational.. or use an alternative, like BSDanywhere (..or preferably just vanilla OpenBSD).

I do not know how jggimi licences his LiveCD's, but he is a member of this forum.. you can send him a PM directly.
Megaupload also seems to require Adobe Flash to upload files, something which is moderately frowned upon in some communities (..like perhaps this one).
