MW: Game Won't Start

[K-z-m-k]

As soon as I add my own m3u playlist file, the game won't start.
I've tried adding it alongside the original empty m3u file.
Changed the 'XNFSMusicPlayer.ini' Playlist file path to match the name if i renamed the playlist something else.
Anything I could think of I tried.

The playlist had 1 song in mp3 format just to test that it works but as soon as I change that Playlist.m3u file, the game won't even start.
