First problem - Can't access Weekly study planner template

Oh dear, I have a problem accessing something I'm going to need from my StudentHome page on the OU website.
The link to a Weekly study planner template isn't working for me - I'm getting a message that says:

I've posted the problem in the T175 tech support forum, along with a few other students.
