set d=0.04 in your password, works for me. I was getting the same like you before setting that.
That did the trick! Thank you, kind sir.
Default X11 diff is set to 0.2. If you have very slow miner, it may take long time for any accepted share to appear. That is why you should reduce diff manually to lower number. It is same with scrypt - if you have slow miner, it takes a while to find a share.
