My product key does not work when trying to convert

[Confused]

I have been trying to convert my trial edition of Microsoft Office Editions
2003 Trial.
The card that came in the package does not work. You claim it is not valid.
What do I do?

Did you pay for the full version? That's a big requirement for the
conversion.
