PROBLEM WAS QUICKLY SOLVED - For those who have similar problems, try disabling your antivirus completely rather than adding GTA 5 Folder to exeptions!
So, after waiting for openIV to fix its issue, I have ran into another. No matter what I try, reinstalling my game & files, redownloading the latest version of scripthookv (Version 1868), redownloading both ELS and TrainerV, I can't seem to get it to work. After looking at it more, I believe it is the problem of ScriptHookV, so obviously I made sure it matched my game version, and it did. I don't understand if I am doing something wrong, or despite both OpenIV and ScriptHookV recently updating, they are still not working. I have also added the GTA 5 folder to my exceptions on my Kaspersky Anti Virus Software. If any of you have any ideas or know how to fix it, please suggest something, I have posted my GTA 5 Main Directory below.
