I have the student version of Mathematica, 8.0.0. Three days ago a popup came up stating that 8.0.1 was available for download. I was busy at the time, so I clicked "Remind me Later." It is now three days later, and I still have not been reminded. I also do not see anywhere in the menus an option to update manually. I have tried turning off the automatic update options, rebooting, then turning them back on and rebooting, but this did not help.
