New graduate student, and this is my first time at Western. When and where is course enrollment?

I completed my program requirements and was recently accepted into MLIS back in June, but I feel so lost right now. I did not go to Western for my undergrad, so I have no idea how any of this works here.

I cannot access my Western email, and I have received no communications as to when or where course enrollment is taking place. I have tried to look this up on the Western academic calendar, but it only seems to have information for undergraduates and not graduates. I'm terrified that I've missed my chance to enroll. I emailed the program coordinator, but am still waiting on a response.

If anybody has any information, that would be much appreciated- thank you!
