Thank you so much for the help, I tried many fixes, removed my second instance of GTA and nothing really worked.

After a couple of weeks, I got the tip from a friend to check the GTA regkeys and then I realized that I hadn't changed my installation follow in the registry. After changing it, all of my scripts started working.

JUST TO START YOU OFF: I've been modding for years so I don't really need a lecture on what's what, I just need help on getting my scripts to start working again.

Basically, one day when I was just feeling like playing some GTA, pressing F4 wouldn't open the Enhanced Native Trainer. I exited the game, removed the ScriptHookV DLL file, the dinput8.dll file and the mod files I had installed. I later re-installed them and tried opening the trainer yet again. This wouldn't work and my mods haven't been working for almost a month now (they stopped working around April 16th.)

So I started looking for help in the ScriptHook V thread on the mods site. One individual gave me a bunch of fixes, I tried them all and unfortunately none would work.

Now, since he's exhausted his solutions, I've decided to look for help on here instead.

Here are a few screenshots:
1 - Game Directory
2 - Scripts Folder
3 - Mods Folder

Here are the fixes I've exhausted:
Re-installing the files.
Downgraded my NativeUI.dll file to 1.7.00.
Trying different Trainers (Native Trainer, Enhanced Native Trainer, Simple Trainer, Menyoo etc.)
I've also tried re-installing GTA V entirely and then re-installing all the other files.

HELP ME PLEASE!!!
