Game Client Bug

I lost my ranked match, and clicked on the continue button to proceed to the end-game screen. All shown-up was a black screen with the "Waiting for Stats" box and the skip button. I clicked on the skip button and normally brought me to the main client. However, when I tried to Q for a new match, it said I'm still in a game and will not able to join Q. I thought this was just my client side glitch, so I logged off and logged back in. I was brought to the game crashed screen with the reconnect button. I clicked on reconnect and wait for 1 min, the client then said It had no connect to the server and tell me to retry or cancel. I clicked retry and the sign repeated. So I clicked on the cancel button and it brought me back to the game crashed screen. It had been nearly an hour already and it's still bugging.
