Misty Mountain track in BFME 2 directory...
OK so Forshire's BFME2 special edition replaced the original track bagood01_t15.mp3 with a track from the Hobbits, inside Music.big within the BFME2 directory.
What Blue, you have to do is reinstall the vanilla BFME2, extract that track, put it inside a new .big file named whatever, and when making the installer you make sure that .big file gets installed in the BFME2 directory to replace Forshire's track.
Unfortunately that's the only way, otherwise we will have to tell people to either reinstall the vanilla BFME2, or include the whole music.big which... would make the patch too big.
Final word: Crap. :/
