Reinstall Office XP on my new computer

[Catherine]

I am upgrading to a new computer. I have already
registered my Office xp Standard for Students and Teachers.
I would like to be able to use it on my new computer but
must re-register according to the software installation.
What should I do.

I also need a phone number to call which I have not been
able to obtain from the website after over an hour of
searching and answering questions on the "support" website!

Thanks
