Refile

After I filed my taxes, I thought I had made an error on my income tax so I clicked on Refile Although realized that I did not need to make any changes and could not cancel out of it so I just clicked on Refile. I received a message that the Canada Revenue Agency was unable to accept your NETFILE tax return.  The Canada Revenue Agency cannot process this ReFILE submission as it appears that the submitted changes to the return cannot be requested using the ReFILE service.  Does this mean that I need to print and mail my return to the CRA or will my original Netfile return still be there and accepted by the CRA?  

Thank you
