Bug in loading screen

Well this is the fourth time, since I have started to play League, that I have encountered this bug.

Here is how it goes down:

-Open Client

-Log In

-Make a custom game

-Choose Champ

-Wait for the 10 seconds to end before the loading screen

-A black screen shows up for about 1 second

-The black screen disapears and I was at my desktop again

-Tried to open the loading screen by clicking on the icon, but the same thing happened. Reconnecting was also no way to come in

Please help me with this issue. I have done some things to try fixing it. I already try to repair the game, but didn't work as well.

Support would be lovely.
