Temporary application PIN isn't working- does it expire?

I applied early action to UB last week. Today I got a text from UB telling me to check my status page for “exciting news”. I found an email that was sent to me shortly after I applied- I had missed it in the flood of other college emails- and it contained the necessary PIN to create a login for my status page. However, the PIN doesn’t seem to work; when I enter it, the login page just seems to refresh. Do the temporary PINs expire? I am planning to call the admissions office when they open, but I’m curious if anyone here can help.
