Can't install/update the mod

I have a legit installation of the base GTA5, bought from a similiar site (legit site) as G2A. Online game works fine in the base GTA5 game, I updated via social club and verified the game cache with it.

I’ve read that GTA5 Online DLCs are free once you’ve bought the game, but I can’t get the mod to finish installation/update, it always says me this:

Do I need to buy DLCs for GTA5 SP or is this something else?

Sorry for double post but I think I might have fixed it (not tested yet). I had social club on non-automatic login but when I set to automatic login so I don’t have to type in my too long password… it started updating almost a 4GB patch… hmh
