I'll just run through a numerous amount of problems I've encountered since yesterday.
-Since I came back from school today, I can't even get into LoL at all. "The launcher has experienced an error. Please restart this application."
-Reinstalling does nothing.
-Redownloading does nothing.
-In the event I do get in, I can't choose a rune page or mastery page as when I choose a character the game crashes for 30 seconds before coming up with an unknown error and displaying I haven't chosen the character when I have.
-In the event the character selection goes to 0:00 and sends people ingame, I have to close LoL and reboot it up to get in the game itself via reconnect feature.
-Profile screen won't let me switch to runes/masteries/champion pages etc.
-Occasionally I get very bad rubber banding ingame.
To further explain all my problems, I had a game yesterday which went swell, we won and hurray for that, but upon joining another game after thats when the problems started ;(.
Also, I'm not sure if I should be attaching a file or not? Halp
