Black screen of death, game crash, network failure, new draft pick.

When i tried playing LoL this morning, my client would only show a black screen while loading. I had to restart my computer several times. It never showed the loading screen only the mouse icon and a black screen i could hear the game but never play. After another few computer rests it finally worked. But alas i was given a leaver warning when i "Had" to agree when i never left int eh first place.

Few more details, i used the new draft pick so after all the banning and stuff that's when the game stopped responding.

My client said i needed to fix my network connection every time the lack screen didn't work. But i was fully connected to the internet. (tested it via web browser)
