How to change the system id on a laptop

[Guest]

I have an Acer one ZG5 laptop and I need to change the system ID. I purchased "RadioGet" great program, but it installs to a specific system ID and they want me to purchase it again apparently cause they won't respond to my emails. If there is a way to change it Please Let me know. I got a worm virus that made it past McAfee (probably my fault) and had to re-install XP.
