Children of Nobody... Ep 9 won't play, trouble loading next 2, then Ep 12 won't play. Next few ok, then problem started again w/Ep 24 and on. Couple times got the white arrow in middle of screen...clicked on it, but it just started buffering and buffering or screen would just stay black. Other odd thing, it was not "saving" episodes watched. BUT..if I tried reloading an episode that was having problems, I would have it marked "watched" in my history!! Weirdest thing I've ever seen on this site. I am not having any problems with any other dramas...everything else in my history plays fine.
I ended up watching on another site out of pure desperation, then occasionally came back to try Viki again with no luck. Don't need it fixed for me anymore, but wanted to let you know in case someone else tries to watch.
