Hello everyone, I'm new to installing mods for GTA V and could really use some help.

I'm having trouble running AddonPeds.

I've followed every tutorial on how to install it, even read the readme file, but
whenever I try to run GTA V with the mod installed, it just closes.

It should also be important noting that I installed an older version of GTA V back in
September when Scripthook V wasn't working.

So what should I do?? delete addonpeds and try again? or remove gta v from my steam library and reinstall it?
what is it I did wrong, and how can I fix it?
