Highlander Orientation Help

So, I have run into an issue with registering for an orientation session to be held in the months of June and August.
The deadline to register was June 9th, 2017; but I was completely unaware of it and I had only tried to do something about today, on June 9th.
I went onto my school account at 6:00 PM and attempted to register for any of the sessions, but every single session was already full. Some of them, DO have Guest Seating available, however… I was unable to register for ANY of the sessions, even before the deadline was officially over.
I have emailed the web address it said I can use to contact them. I explained every bit of my situation, even down to the last minor detail. This was at least at about 6:30 PM.
The orientation is mandatory for me to attend this school! I am greatly stressed and deeply worried.
Is there any hope for me?

There’s a handful of people that I know who still haven’t signed up for orientation because the sessions were all full. I think you need to wait a few days until they add more dates because there’s just no way they’re going to rescind acceptances for all those people who haven’t signed up for orientation yet. Same wth the immunization records - the link doesn’t even work for me but they said the portal would open on June 1st. I think we all just need to wait it out
