Okay. I have done the Anti-Virus part but the RagePluginHook Launcher still won't start GTA, just keep on loading(it says launching game...) till the end of times.
Edit:OMG... I've just sold the problem...finally!!! I was so dumb. I left the old RPH shortcut on my desktop and didn't realize. It opened the old one every time I tried to start the game. Sorry for wasting your time, and thank you for helping me out, it means really much to me.
