I recently re downloaded GTA V so I could play LSPDFR again. I downloaded RPH and everything else necessary, as well as police vehicles and a siren and some scripts. But, every time I run RPH, it takes a while then says "Bad Antivirus or Insufficient Permissions". I disabled all AV and ran it in Administrator mode, as well as trying to start it while the game is already loading which worked last time I had the problem. But now, nothing I have done or been told to try has fixed it. I'm currently making a backup on a different hard drive in hopes that it fixes. Does anyone have any idea why this is happening, and any solutions? Thank you in advance.
