Contact ProcturU through their chat. They can help you reschedule for tomorrow, only if you hadn't started the exam. Some got booted while mid exam (that really blows!) and they will probably have to wait for further instruction from LSAC. I was able to reschedule my exam through ProcturU (it was scheduled for 11:40 this morning).

I had the same line of thinking. Still can't quite make sense of it
