I've just checked and can see Nuts pool hasn't found a block in 65 hours which is why your shares are stuck.
The block chain is working correctly as I can see its still advancing, so at a guess the problem lies with Nuts pool.
I'm guessing something on his pool has crashed which is why its not finding blocks.
Hopefully it fixes it soon


I've just sent the Nut2 pool owner a message on Skype so hopefully he see it soon and fixes his pool
