There is an issue with the Sage software that requires reactivation on opening. We will begin the process of fixing this today, but it may take a few days to get through all the machines. College of Business is experiencing the same issues and are already in discussions with the professors that use it in hopes of moving to a different software platform for spring semester.
In the meantime, if approached by a student with said issue, they can just hit Yes and the software should reactivate after a couple minutes.
