I assume you might have started on the bad chain? Or got forked off right at the beginning when there was much strife on the network.
In any event I would suggest turning off wallet. Removing Peers.dat downloading the blockchain and txlevel from hobonickels.info and start up with connections from cryptopia or from Explorer.
Also before you go can you type getpeerinfo in console and send it to me.
