Sorry Thomas, I meant to be more descriptive about the problem. The intro scene is gone altogether. When "New Game" is chosen, it goes to the loading screen, then immediately to Daniel standing, skipping the intro flashbacks. But the game itself functions perfectly.
As far as the hpl.log is concerned, I don't know where the -WARNING: Could not find language file entry 'english01'- is coming from, because the only language file loaded is the standard english.lang, unless you load a custom story, in which case, the other extra_english.lang file is loaded, but I don't think that is the cause of the problem. However if you see anything that I missed, let me know. Thank you for the speedy response.
