What is the exact error message that you are getting? If you are getting a NETFILE error saying your account is locked, you'll need to contact the Canada Revenue Agency (CRA) and ask for your NETFILE account to be unlocked.

If you are in Canada or the United States, you can call the CRA at 1-800-959-8281. If you are elsewhere, you can call 613-940-8495. This page has more ways to contact the CRA: Contact the Canada Revenue Agency
