GTA5-Mods.com'a hos geldiniz

Hello, I installed as instructed, however, I couldn't find "scaleform_generic.rpf" so I searched it using OpenIV. Once I found it in the mods folder, I proceeded. This might've been where I went wrong, however, I'm not sure. Then, I had an issue with the game version and ScriptHookV so I changed the GTA5.exe and PlayGTAV.exe files to the older versions with a file I found online. Once I did that, the game launched as normal. Then, when I hit Story Mode, it crashes. I would like to know what file could potentially be at fault here or if I screwed up by going in the wrong folder or anything. Any help would be appreciated, and I would also like to know if the radio plays through other sources in game than cars (Like Franklin's house on the hills with a radio in the rooms) and whether that's even possible without Spotify allowing audio through their API.
