Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.

I finished step 64, got full grades for checkpoint 1 and 2 but got stuck at Step 65 and 66. I am able to go to the "Meeting" page but cannot find the "New" button next to the "Delete" as described in the instruction. The grader also says to continue and complete from step 65 but I cannot proceed because I cannot find the "New" button. Below is my screenshot. Can you please tell me what to do next? Thank you.
That’s because you clicked on details on the left instead of fields and relationships, which is just under details. Click fields and relationships and then you will see the new button as described.
