I've been intending to put up the English version files on our FTP, but I'm not quite sure if that would be legal. I'm inclined to believe it's legal, firstly because they can't be used without having the game in the first place, and secondly because Xenophonia has not been in any trouble for redistributing files from other language versions.

I guess you've left a long time ago, but there are more suggestions in the validation post.
