nevermind! did this and it works-
Things to try ...

Try each miner to see which one works for you.
Make sure everything in config.ini is correct.
Backup config.ini. Try deleting the witness_node_data_dir folder and restarting, exit with CTRL-C when you get the message about config.ini. Recopy config.ini into witness_node_data_dir and restart then let it sync without adding blockchain file.
