Just so that no one has any questions on this. I just bought the game yesterday 4/25. Installed it and then did the 1.03 upgrade. Stated the game with the trainer and it crashes after about 30 sec. Uninstalled/reinstalled the game and then patched to 1.03. no trainer works great.
I've tried that as well, still didnt work. What I may try after I get off work is backing up my save games, un-installing GTA4 and GFWL, reinstalling and manually patching from the websites, not in game and give that a shot. Its the only thing I can think of at this point. 🤔
