I can't see my Match History and something else

Everytime I click my Match History, that's what I get. And also my Runes page gets confused, all of them turn into giant runes (they don't give me any extra stats in-game when that happens, unfortunaly -kappa-). I just changed regions (Brazil to NA), since I moved to Boston. Please, gimme a solution. Appreciate a lot any help.

I LOVE LEAGUE OF LEGENDS!
