THE PC WHEN I PURCHASED IT), BUT IT KEEPS TELLING ME THAT IT'S
INVALID. I ALSO TRIED TO DOWNLOAD A NEW 60 DAY TRIAL OF OFFICE
EDITION 2003, BUT THAT PRODUCT KEY DOESN'T WORK EITHER. CAN YOU
PLEASE HELP ME

Your keyboard is broken: the shift lock key is stuck.
Please replace the keyboard, it's probably still under warranty.
