5.5 front page blank

Me too, and shortly after I see this screen my entire computer freezes .........

Same happened to me. My computer froze and crash, but not I can no longer launch league at all

yup the same whith me plus no fatal freeze of my computer

I'm dealing with something similar to this... almost every time I leave a game the last several day to a week, it doesn't take me to the chat and freezes. I can't alt+tab out so I go to task manager... it'll get me out, allowing me to use my tool bar, but my screen stays black besides that, even when I open things up, the black screen stays in place until a crash report is conducted. After that, it puts me back in the chat after everyone has left, etc. (really sucks after this last match... two guys were really trolling bad in the opening lobby, then sat at base after everyone eventually lost lane... wanted to report them for being scrubs)
