I am using Profile FX to prepare the 2024 T4's for my clients.  When I try to upload the .XML file from Profile through the Represent a Client portal an error message comes up and will not allow me to continue with the efile.

This is the error message I am getting:

Error: We are unable to process your submission because the transmitter CRA account number given in the attached T619 electronic transmittal record does not match the account number you used to sign in.

I have double checked my account numbers and Rep ID in Profile and they are correct and I use the same Rep ID to logon to the Represent a Client account.

Does anyone know what's going on and how to fix it?
