Okay. So the error is a text character that the engine/font can't render. Because you said the Singles chart was missing an entry, I'm going to bet it's a rogue song title that slipped through with a weird apostrophe or something. (I don't think it's a band name or else this would be a more common issue.)
Your options are ... send me you save file and I'll try to salvage it (maselphie AT gmail), or remove all/some song titles from the song titles TXT file until you find the problem. That MAY work, I don't know. >_> I'm sorry this happened.
