Missed orientation day

Hello, I am an upcoming freshman for the fall term at CSUF and I just missed the whole Orientation that I was scheduled to go today because I was working late and overslept. I am really stressing out now because I do not want to be denied at this college. I have called them and they said to make an appeal on the website which I already did. How screwed am I?

Also, there is an option to enroll in classes on their portal so I’m not sure if I can register for my classes in there or not.
