Interesting, since we've had customers in the past submit without requiring this access ID number. I did myself just log into my ticket system account using the url above and it wouldn't let me past the access ID area. As such, could you ask your provider to submit a ticket on the issue?
It might be we are now requiring this to ensure that the user is not a cPanel level one. In the past, we've had website owners report issues where they are on a custom theme and the theme itself is the issue, and it was something their provider should have been asked about rather than reporting a bug.
