So, I downloaded GTA V (worked perfectly without any mods), made a copy of it and downloaded LSPDFR latest version 0.4.9, did the file transfer to the main game folder correctly, included all the needed files and changed the RPH settings to download the LSPDFR during the first start-up
but then...
When I tried to start the game via RPH (after opening it, my PC opened the Rockstars game launcher where I pressed "Play on Steam") Steam opened and I got a notification saying that I'm missing a file. (NOTE: I downloaded and transferred only the files within the LSPDFR (manual, not auto) file.) Right after that, Steam started to download the whole 105GB again saying that it was an update, not to mention that I couldn't even play the original, clean GTA V since after trying to open the game via that clean folder that didn't have any mods or plugins in it, it would open Steam and show the uploading process. So at one point I had like 4 full GTA V files in my PC (deleted them all and now downloading the clean version again) but I'm a bit afraid I will still need to do something in order to get the LSPDFR work. Any help, what should I/can I do to fix this?? I've been waiting for my gaming PC forever to get this so please... Thank you so much in advance.

I will continue to try to get that work by following different guide videos from YouTube. I'll edit this post if anything changes.
