Leavebuster Bug "I Agree" doesnt work!

Greetings Summoners!

I recently played a match and disconnected for about 7 minutes due to a power outage in my neighborhood. When I got back into the match, it was already 20 minutes in and the game was almost finishing. The match ends and this Leaverbuster message pops up, ordering me to type "I agree" inside the box. When I do this however, it won't let me go through and click "ok". I tried using capitals, lower case letters and any variations of it to no avail. I also tried restarting the client, but the same message pops up interrupting me from doing anything in the client.

Has anybody had a similar problem? Looking forward for your answers.
