I've been putting off doing these returns, because I know something will always go wrong. I've managed to overcome various error messages, but now I'm stuck with:
Authentication Failure
Supplied user credentials failed validation for the requested service
BodyError Code 1046
I'm using the same computer as last year, when the return was finally accepted and went through successfully. This year, the computer remembers my PAYE user name and password. But I'm getting the error message above. I've tried deleting the PAYE user name and password, and then re-entering them manually. But still the same error message. My user ID and password are definitely correct. I've tried rebooting the PC, re-entering the name and password loads of times, triple/quadruple checking for capital letters and confusing numbers. And still I'm stuck.
The PAYE on-line helpdesk of course blame ABC. They've asked me to get ABC to remove the autocomplete fuction, so that I have to manually enter the user name and password when the return is actually being sent. Can't see what difference that would make. But they won't offer me any other help apart from that.
What should I do?
