I am at 81% completion, and when I tried to resume, I simply can't. Attempted to log out of the system, tried different browsers, and tested at other times, but no matter what I attempt, I got the same message in the picture attached. I don't know how to overcome it; unfortunately, my extended DB connection expires in about 21 hrs. What can I do? anyone? ideas? I am so close to finishing this class and I am trying not to have to start all over again because of this state.
