Attempting EFILE-Getting error EFILE#1003

Newby here. 

Got my first T2 return EFiled no problem. Shows as received in the CRA My Account.

Now attempting to file the T2 for the same company for the subsequent year. When attempting to transmit, the CRA message indicates non-acceptance......"error EFILE#1003". Also indicates that I must answer "NO" to "I want to sign up for Online Mail for my T2 account" but when I go to the Info form in ProFile it prevents me from answering NO. How can I override or correct this issue?
