This is a fresh install of GTA 5, with GTA 5 redux mod, followed by LSPDFR, followed by RPH. In that order. And then of course Traffic Policer. I am using a "mods" folder as per OPenIV suggestion. with the install of Redux in their as well i suppose, since thats where i chose to install it.
If its any help.. the crash is just "GTA 5 has stopped responding" with an option to debug or close program. Then social club window pops asking for safe mode, etc.
