By calibrated you mean the shortcut is set to open in I.E.? It has iexporer.exe in the shortcut? Or was it just because I.E. was the default browser? What version of I.E.?
If you copy and paste the shortcut to I.E. manually does it work? Try it on another computer. Just go to the web page directly, don't need to save the shortcut.
Are you even looking to fix this even or will just use Firefox?
