Flash Player won't play movies on putlocker.com

I am unable to watch movies through putlocker.ch now, and I used to do it all the time. Once Adobe Flash Player is up, I click to play the movie and it loads for a moment then displays the message within the following parenthesis (200, Stream not found, NetStream.Play.StreamNotFound, clip: '[Clip] 'http://s2.putlocker.ch:86/5409.mp4?key=c107408b1f62e4c4c670b51d668f7b4a'') can somone tell me what I need to do in order to allow Flash Player to play the movies on putlocker.ch  ?
