I seem to have missed a few posts: The box is a leftover from the Barbarian World option, which was removed because it didn't work. Well, thanks. As for the bug (I noticed the same report on the DL page), I'm afraid I've got no clue. I got the same thing myself when trying to load Babylon 5 v. 2.7... 5.3 has been reloaded on StrategyInformer, plus there's an alternative download from Rapidshare (you can check here: http://forums.civfanatics.com/downloads.php?do=file&id=19066). Hope that helps.
