Create a copy of your GTA (Grand Theft Auto for steam) file when you want to play LSPDFR. Call it GTA OG (Or Grand Theft Auto OG for steam). Make sure that this file is your ORIGINAL GTAV files and NOTHING else. This is so you can just rename the modded version of your GTA back and forth depending on if you want to play a modded version or not and you don't need to reinstall an entire game. The game launches off of what is called the default file name (GTA, Grand Theft Auto) so if your Ragehook is in the default, you will load the ragehook stuff. If your original files are in the default name the game will load without any mods allowing you to play online.
So when I fuck up I basically delete my entire GTA file and have the GTA OG sitting there ready to be copied again so I can mod it. I make a copy (it will be called GTA OG - Copy) and then I just rename it GTA, install the hooks and plugins etc and start a mod file from fresh.
