How do I record matches after patch 4.20?

I like to record my league matches. The problem is that every since patch 4.20 nothing works. Not baron replays or league replays. I've just tried to record a match using op.gg. It said that recording was requested after I clicked the red record button but there is no replay button in my match history.

What can I do to record my matches? Things like Fraps are ok but they only record what's on my screen and I can't see what other players are doing while watching the replay. Something that allows me to replay the match through the client would be best.

Any ideas?
