I'll do another build with some more checkpoints later today.  The problem is that CPU Pool was off on a fork for awhile before they updated their daemon.  I'm guessing they did not rescan the blockchain.  The coins between block 8600 and when they updated will have invalid difficulty.

What you can do is add this line into your .conf:


or run the wallet or daemon with -checkblocks=0 on the command line.  It will take a long time to start up, as it will doublecheck every block in your chain.

Supernova was updated right when the new daemon was released, and the exchange shortly thereafter, but everyone seems to be piled up on cpu pool.  Its not good to have all the hashpower concentrated on one pool.  Spread the love around to help distribute the hashpower.

I'm tempted to set up a pool myself to distribute the hashpower more...one thing I have not done yet is operate a pool.
