Okay. Well, what I found out was this. I had gotten to a point in the offline story, right after the mission where you are scouting for the big heist, and right before bury the hatchet.
Nothing was moving forward, I did every side mission for both Trevor, and Franklin, but cant utilize Michael at all.
I too, am winning completely LAUNCHING or, waiting for other players.
here is what I found out.
Uninstall your game, then reinstall it, BUT DO NOT INSTALL THE GAME DISC.
The first disk yes, your game disk no.
FFS. All I see is people online, and yet, im sitting here waiting to LAUNCH.
