How do I get start Microsoft Office?

I bought my labtop computer in the end of January, 2005. I remember that I
entered the product key(the trial key) to start Microsoft Office program at
that time. It had been doing well until these days. However, the office
program haven't worked well, and got a message "Invalid product key" error
message even though I entered same product key. I don't know the reason.
Please help me.

Wonseok Lee,
The trial version is good for 60 days.
If you are trying to install a purchased version, uninstall the trial first.

If this article does not apply, please post back with more information on
why you were required to enter the product key again.
