@JohnFromGWN Thank you for trying to help me. I really appreciate this!
I did these suggested steps. but not working. When opening the game, this message appears: ERR_GEN_INVALID
Corrupt game data. Please reboot, verify the game data, or reinstall the game. For more information, please visit: http://rsg.ms/verify
For this mod, it allows me to play the game online without an internet connection. I can't explain it in detail, you can read more about here
And if u want to try it u can download it. Thanks!
