yep, its looking for the genesis block which hasn't been created yet. only happens if you don't have the blockchain yet. wierd i know, think it has something to do with the script used to create the genesis hash/merkle root. shakezula made the mehcoin repo(which this is based off of) so it included his special little function for finding the gen hash/merkle/nNonce(nunce) easy. should only happen once.
