As someone else has suggested (and it worked for me once):
1) Try removing all the pools, then re-entering them
2) If you have more than 1 blade, set a unique entry in the pool list with a unique worker name for each blade.  Then assign each blade from the drop-down list.  This way you can monitor each blade for problems.

From my own experience, set your worker/share difficulty on your pool to 1024 or 512. Share difficulties of 16 or 32 make the blades perform unreliably, in my experience.
