Apparently i cannot record, i accidentaly turned it "off" and cannot turn it on again
Usually the fields shown are grayed out if you're in the middle of a game. Are you able to turn it back on if you leave the game?
I'm a but late to the game here,and you may have fixed this by now, but here's what worked for me.
I had the same issue. I did a first-time install of Raptr/Plays.tv Friday and on Saturday I was messing with Settings and turned Gameplay Recording Options to Off. After that I could not re-select either Automatic or Manual - they were simply not clickable - as inthe OP's screenshot.
I closed and restarted the app and still could not change. So, I uninstalled Rapr/Plays.tv and re-installed and that fixed it. You should be able to re-install just Plays.tv without doing Raptr also.
