I've stopped modding GMod so I won't be fixing it any time soon. You can extract the addon using gmpublisher and then edit the lua file yourself, I won't make a fuss about it.

That being said, when you report a bug or the addon not working, please do so in a way so I can understand what's not working. As in:
- when does it not work (what do you do for it to not work)
- what sounds aren't playing

Though I've used this pack myself quite a bit since I like it and never had any trouble. Check your console if you get a soundcache overflow error, if you have too many sound addons that add a lot of sounds, some sounds won't get loaded because the cache table is full. Each sound file will get put into the cache table for ease of access for the game. The limit is around 16000 files
(as a TFA-VOX modder I've reached that limit easily)

TL;DR

I stopped modding, won't fix. Make better bug reports :P, you can extract and edit the LUA file yourself no questions asked, check error messages.

dont know if its a bug or what but sometimes the voice lines do not play can you fix that later pls?

The Mindless Fun(tm) Vault Hunter. Not a bad thing because having infinite ammo on just about all weapon types is pretty great.
