Because of error, I dropped my lp

I was on loading page. And the error sound popped up. And I tried to see what the error is, but Alt + tab didn't work. I tried window + tab, ctrl + alt + delete, close all the tabs, (even though all the tabs are closed, the loading page is still up..)

Well I'm not saying that this is riot's fault, but you should at least give my lp back. If giving lp back is impossible.... well then I'll just play......
