Activation link does not work

When I click on the activation link ( https://deimos.apple.com/WebObjects/Core.woa/Activate/montereylaw.edu/004d93af83 dc73e45cb47dc42255d0419e7c20295e55e41afe46dbbbdb28956715450886c5) I receive an error error message box that says, "We could not complete your iTunes store request. An unknown error occurred (-9812).

I tried the link from my work desktop, personal off network laptop (windows vista) and an iPad 1 and received error messages on all of them.

Any ideas?
