Cannot get into queue for a game

Hello,

Tonight I am experiencing a strange bug with the client. I logged on to play a match and selected Play > ARAM, then minimized the screen so that I could look at something else. When I checked back on the client, I saw that there was no timer for queue and instead the big orange "play" button was in its place. Naturally I assumed I had missed the match and had been removed from matchmaking, but when I checked my notifications it said no such thing. I tried to enter the queue again and found myself only able to return to the main screen with the "play" button still in place. I tried different queues including normal draft, all the co-op AI options, and even a custom. All resulted in being returned to the main page with the "play" button still available except for the custom match which brought up a big black screen that I had to click out of by accessing my profile.

I cannot play a match at all and this is very frustrating for me. Is anyone else experiencing this bug?

Thanks for your help
