League won't load

So after champ select the screen goes black, but instead of the load screen appearing after a moment I get this pop up on a black background. This is after I have played many games and have been connected to the server with no problems. Internet is working fine as well, less than 25 ms constant. Also after the game was lost/remade I was loaded into the after battle report as usual, connected to chat and everything. I am able to get back into a game right away as well. Please fix this.
