A timeout or token validation problem has occurred. Please close this window and sign back into this CourseBuilder site as you normally would.
A user, perhaps you via another browser or computer, or perhaps someone who has your Dashboard credentials, has crossed into your CourseBuilder account.
Because CourseBuilder only allows one concurrent session per user, the session you have been using is now terminated.
CourseBuilder times out if you have been inactive for 60 minutes. If you see a Continue link below and click it, CourseBuilder will see you as active for at least 60 more minutes.
However, if you don't see a Continue link below, you have timed out, and you will need to close this window and cross back into this CourseBuilder site to continue using it.
