cd in the folder containing the executable (windows or ubuntu) and
darkcoin-qt -reindex
darkcoind -reindex
Or delete everything in the darkcoin folder
except the wallet.datIt stuck on some block number again!
Some masternodes are destroying whole network. There are so many block chains.
./darkcoind stop
mv darkcoind darkcoind_100806
wget http://www.darkcoin.io/downloads/rc/darkcoind
chmod 700 darkcoind
./darkcoind -daemon -reindex
should actually get you going!
you can check darkcoind's cpu usage using "top". While it's reindexing it should be using >>90% cpu time
