Can't press "play" after I logged in

When I log into league everything seems to be working fine, that is until I realize I can't click on the play button there for not being able to actually play league. One other thing I noticed was that I can't right click friends, but everything else seems to be working (Shop, profile etc.). Anyone have any thought's on how to fix this, I would really not pref re installing the game. (mb forgot to put in title "Client error")
