Greetings --
You need to examine the Product Key very carefully. It's awfully
easy to mistake a "B" for an "8," a "G" for a "6," an "S" for a "5,"
or a "Q" for a "0" or "O." Fortunately, Microsoft had the good sense
to leave the "1's," "I's," "O's," and "0's" out of the equation.
Also, be sure that your <CapsLock> is _off_ while entering the
Product Key.

To recover a lost Product Key:
If your system still runs, you should be able to use AIDA32
Enterprise from
http://www.aida32.hu/aida32.php or ViewKeyXP from
http://www.webtree.ca/windowsxp/repair_xp.htm to find the Product Key.
(If you have a factory-installed OEM license, and haven't since
reinstalled the OS, the revealed Product Key is probably of the drive
image used at the factory and not _your_ specific Product Key;
therefore, it probably cannot be -- and definitely should not be --
used for a re-installation.)
If it was a retail license and you have proof of purchase:

If it was an OEM license, you should contact whomever sold you the
OS; although very few manufacturers/vendors keep records of the
Product Keys they've sold, it's worth a try before you have to buy a
new license.
