I've been figuring out how to get my own tracks to play in multi theft auto and i've noticed that it uses the ADVERTS file, but when I remove this I get no sound? I've tried refreshing and also set it to auto update to search for the tracks but still nothing, is this normal or can I get my own tracks to play somehow? I've also set my tracks to MP3 format so shouldnt be a problem...
