Activation - Part 2

I wrote early this weekend of my frustration at being unable to activate my copy of Windows XP. As the time draws near for the opening of MDG's service department (my copy of Windows states they're open at 9:00AM - their website says 10:00AM), I decided to get my ducks in a row by verifying (for the umpteenth time) that the online activation process I attempted on the weekend was unsuccessful. So I entered the code yet again, fully expecting an error message. This time, the activation worked. No error messages... just a note informing me that the activation was successful.

I just don't get it, but at least I won't be as embarassed as if this procedure had worked while on the phone with a tech!
