code: The software mined the wrong fork because of a faulty RS2 transaction, you have to rescan or rewind
Ive tried "scanforalltxns 600000" now, result was scan completed. But still stuck on block 616098

1. "rewindchain 1000" in console
2. Close Wallet
3. Delete peers.dat from app directory
4. Restart the client (now this may not work since you might be banned, if so leave your client off for 12 hours)
5. Check the block height against shadowchain.info once you are fully in sync.
6. Finally for sanity and reassurance run "reloadanondata"
This worked! Thank you.
