hm ... one day befor i'was move my miner to v.5.rc2
i'm sorry about that, but i guess it's just bad luck for you. there's no perfect timing for such a huge update.
you'll have a few days to update your miners.
other question what is with the coins what was mine and was not pay out?
like i said before:
the blocks from the old payout system will be executed once they are confirmed by the primecoin network
just like they were paid before the cppsrb update (this will take ~2.5 days for all remaining/needed confirmations)
the new payout system will kick in once the confirmations are through from now on
expect the first payout for the new cppsrb system in ~2.6 days (+ some delay due to monitoring setup)
