The change to the block reward did not work as planned as the longer chain was on the old software and the new client did not mark the longer chain as orphan but assumed the longer chain was correct and the current client out of date. Please downgrade to the previous version of Hirocoin which is 0.8.6.4 for PC and 0.8.6.3 for Mac.

A test environment will be setup to emulate the network at the time of this hard fork so changes can be made so the new network protocol does not get confused by a longer chain on the old network.
