BU web account login

<p>I sent in my application from the Common App about a week ago and I got my email about creating a web account for BU. A link was included in this email to set it up, but every time I try to click on it the page that appears says “This URL is not valid or has already been used to register an account.
If you have already completed account registration, please go to:
account sponsor
and use the password you selected to access that information.” </p>

<p>I never set up an account so I was wondering what I’m supposed to do exactly to create an account.</p>
