I finished the lab 1a and 1b at the same time. I also got 100% for lab 1b, but I forgot to grade for lab 1a before I did lab 1b. That's why I got 0% for the lab 1a. Can you give me the certificate for lab 1a, please.
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.
