So whenever I try to launch rageplugin hook to play lspdfr I get the error message "slow system or insufficient privileges" or "bad antivirus" I tried using the discord, all solutions they had did not work. Did lspdfr update or something? How do I fix this?

I am not quite sure what help you got, so I do apologize if some of these are repeats.

1. Add GTAV folder as an exception to your antivirus. Search online for how to do so according to whichever antivirus you have installed.
2. Open your main directory, back out once (so you see your folder itself)
   1. Right click on the folder and open properties
   2. Go to the security tab on the top of the popup
   3. Give yourself, system, and administrator all permissions, save and close. 
      • Special permissions are unneeded and provide no benefit to your neccessarily.
3. Make sure your computer is not using its resources excessively on another application, as sometimes that can affect runtime depending on the computer you have.

NvM Just installed something incorrectly in Open IV. I deleted the mods folder in Open IV and the game  works fine.
