CAN'T DO ANYTHING AFTER I LOG IN

Dudes, help plz. After i log in, and it comes to the lobby, then it turns a slightly grey-ish like when you gets a crest, or when the leavebuster somes up, or when it informs you comes in a new league. I can't click anything, and i wait a long time without result. PLZ ALL OF YOU LOL GAMERS OUT THERE, HELPPPPP ME I can't play lol while it's like this, and im dying right now ;(
