Can't drop classes in Telebears?

<p>I signed up for Math53 just as a backup for my waitlisted Math1B. I just checked today and I'm now enrolled in Math1B, so I want to drop Math53, but the Drop Class button to the left is gray. But on the top of the page it says "Fall 2008 appointment has ended for this phase. You can only review and drop classes." Could someone help me with this so another person can take my spot?</p>

<p>You can only make changes to your schedule during open hours</p>
