The other day I installed a couple new trucks, and decided to play the game for the first time in a while and then I noticed that my sound wasn't working on alot of my trucks. I cleared cache, and nothing. I then re-installed the beau4x4 sound packs (even the updated one) and still nothing at all for some trucks such as the edelbrock truck, and heavy hitter . I have no idea what to do, any help is appreciated. Thanks in advance.
