Is your pool actually correct ? I see quite some differences in the current block being displayed by various pools, yours seems to be ahead of all others....
I installed the latest client per IceCube and soopy452000's work.
Not sure what else to tell you. Pool runs just like all of my other ones. No errors in logs, etc.
