Beta Client Bug (can't go back to homepage)

So after a game of league, normal draft queue with my friends (5 group) I left the lobby and couldnt find anywhere to click play game, store or profile, so I clicked the link which said free week champions which is what you see in the picture and I cant find my way out of it.

Only had the new client for two days, so dont know how frequently this happens but I will update if it does.

There was supposed to be a pic here but this website doesnt let me to upload it clearly since it wont bloody let me use my screenshot.......if there is a need for a picture riot I can send it through email at request.

Regard,
