FS2002 internal compass problem

Hello, I have a problem that I cannot seem to fix. Every time I go to KLAX, the internal compass is switched around 180degrees (I am on runway 07L and the compass is reading 241, even in the Shift+Z thing, which is way off.) I have gone to the map and the thing on the bottom that tells you all the runway headings is even reversed, but when I checked the airport is AFCAD, it is fine. This is a very weird problem, and any help would be appreciated. Thanks.
