I purchased an HP notebook computer that has Windows Vista Ultimate (64-bit)
installed on it.

I ran into a problem and was attempting to get into email or chat support on
Microsoft's site. At first, I mistakenly chose just normal Windows Vista
Ultimate, and entered my product ID. The site responded by telling me that
the ID is a 64-bit ID, so I went back and chose Ultimate 64-bit, and entered
my PID, and the system tells me that it's not a valid ID.

Is anyone else having this problem?
