Sorry, not buying this.
Both my pc have been farming ETH and got over 6 of them in the past months.
Similar with my friend who had the exact same result.
lets see what happened. start `geth` and do this:
> eth.getBlock(0)
in the output you will see the "hash" field and it must have this value:
hash: "0x13771466fee63d1916818f25c5e2ed5e09330b9fccc8da760c172d09412680d4",
If it doesn't have this value, then it is not our blockchain.
If it does have this value , then do this:
> admin.peers
and it must show a list of nodes. If it is empty, then you are not connected.
