Hi, I can submit VAT returns through Sage 50c, we have the latest version etc, but it will not let me submit the EC Sales List. It comes up with error code 1046, which is an authentication error. The solutions seem to be, check you have an up to date version, which we do, check your credentials, which I have & delete all your credentials & try again, which I haven't done as it will submit the VAT returns. Any ideas?
