I don't think anybody else has this EXACT problem, but, what happens is that:
1: Open client.
2: Hit launch.
3: Wait (2-7 minutes)
4: Nothing happens from it.
This has been happening for almost a week now, and it's happened every single time i try to open it. I'm VERY mad because of this, and i really want to play!
EDIT: Also, i should note that i have tried deleting files, going to the source league folder and running the launchers in there, and deleting client updates and re-installing, if all else fails, will complete re-install.
