ThemeParseLog Errors

[Admiral Stephen]

I got this from the "ThemeParseLog" file in my Beyond the Sword directory. Before I post the contents, the problem is that certain pop-ups (Civilopedia and options) don't appear when clicked, and I have no HUD/interface when I start a game. The game itself still runs, I can play it so long as I know the hot keys for everything, but I have no interface, no map, no nothing.

Anyways, it says

"[May 23, 2008 - 00:37:48] Messages while processing 'Resource/Civ4.thm'

How can I fix this?
