Left4Dead2 Visuals Multihack

I have a question, how do I install this expert config?

in your game folder you will find a file called config.dat

I've returned to this game after a long break and i've just downloaded and configured the multihack but i keep crashing. Either when tweaking the hack or when trying to join an online lobby.

https://we.tl/t-kZuwnL4LFV - here are my crash files and the config.dat file. Hopefully you can tell me what's going on and why because it really doesn't make any sense. Bought a new laptop, installed l4d2 and downloaded the multihack. I also got the directx and the redistributables installed plus the dependecies. I'm pretty sure everything is in order. Otherwise i dont think the hack would have showed up ingame at all. But i can't tell which setting is causing the game to crash so aggressively.

hi, try the version I sent somewhere above and see if it happens too

and.. weapons info method 2 crashes the game in that version too

Tried your suggestion and the same. I don't use weapons info method 2 so what gives?

Also, how am i supposed to use the M1 and M2 actions? How to make them work? I mean to instantly revive, heal or defib someone because these options don't seem to work. They rarely do. 

Also, are there any experimental, or in progress features that i should stay away from until a newer version is released?
