I managed to get two of the three files, namely enwiki2-2007-01-05.dct (546MB) and enwiki3-2007-01-05.dct. (569MB) I wasn't able to get the first one yet. I'd be happy to upload them, and the first if I get it, to someone to host, but I can't host a bittorrent myself, and don't have bandwidth to just add them to my website.
