Okay so I installed my legit copy of GTA IV which I bought in 2009, entered the cd key, it verfied and all good.
When I launched GTA IV it said GTA IV has stopped working. When I created a commandline.txt and downloaded a xlive.dll file, that problem was solved, GTA IV launched.
New problems - I can't change the graphic settings, they change for some miliseconds and go back to original.
Also, on starting the game, it gets stuck at the characters loading screen endlessly.
Help pls.
PS - Downloading patch 1.0.7 as I write this topic
Also - i7 somethingM quad core
8 gigs of RAM
Intel HD 4000 (I know damn well it will run at low settings)
