Game still in progress

Hello Everyone!

In the past few days I got an error when I start a game. Everything black client is running nothing happened. I close everything start run as administrator and i have a message "Game still in progress" after a few try Im in and the match from the match history is dissapear, doesnt exist.

Have you ever had this problem? IS this from the server, when Rioters do somethin (update, changing , etc.)
