SO I saw a few posts regarding RPH stuck on "launching game" which is what mine does...
My LSPDFR is the newest version, clean installed GTA V GTA V Main directory and RPH.exe is in my AV exceptions list..
It still gets stuck on the Launching game stage.
What I realised is that if I go into the Main directory and start GTAV.exe it starts the game, and when I then double click on RPH it hooks correctly, but GTAV.exe is the redirect exe to start the Rockstar Launcher version of the game, not the steam version, so when it gets in game successfully hooked it says that I should activate GTA V on rockstar games. I cannot get past that
SO seemingly the problem is a Steam account problem??
