I ordered it last Friday afternoon from the Wisconsin educational website. They delivered it today.
It is, indeed, CS 1.3, as I figured it would be (since I did order it, after all).
They must have actual inventory, as the package came from the Wisc address.
So now what do I do to find out if I can get the upgrade? Michael, you said there's a number to call for the Wisconsin site? Or should I call Adobe instead?
