Did you ever get your DCY?  If not, it's a problem with your local wallet / blockchain data.  I was on the same pool at the same time and I had to follow Flong's instructions exactly to get my old wallet to update and sync properly...  it got all of my payments those days, from the exact same time frame you are reporting on...  I can tell you, the pool doesn't seem to have been on a bad fork.  I got paid just fine.

The pool paid... which means they are on the blockchain waiting for you...  you (the SW) just have to grab them properly.  Let us know if you still need help getting your payments?
