Sorry, I can’t recall if a link became active or if students received an email with link and instructions for creating their email. The error message may be your culprit. It’s also possible that the part of the system that confirms receipt of a matriculation fee doesn’t update immediately with the part that changes the graphic interface to say “acceptance”. The error may have put you in some sort of limbo. Call the bursar or registrar tomorrow morning and they should be able to get you taken care of.
