You upgraded Ensign version2-03 but you did not upgrade the IB TWS.Quote from CAzzaro:
I just upgraded to Ensign version 2-03, and I now have the same problem. I did not upgrade TWS.

You should try to upgrade your IB TWS to 856.4 and use the NEW IB TWS shortcut and then check again and if you have the same issue then you just reinstall Ensign upgrade 2-03 again.
That is what I did. It's working fine for me.
