Hello again, yes my GTA is working just with LSPDFR and some callouts with vanilla cars and peds. And yes, I installed everything like you said, into GTA folder and into mods folder and update.rpf/common/data with OpenIV.
My game is crashing when I use asi loader from OpenIV ASI manager, without it everything is working fine.
I tried to use these car mods, new EUP and this uniform pack from Sam:
This is everything I'm trying to use. Thank you very much for your help man.
