Geri is having trouble with software she bought. When she tries to send in for the activation code, it says her "machine ID" keeps changing. Leo says that there is no such thing as a "machine ID." Often, copy protection has to phone home to authenticate it, and if the company website is down, it won't work properly. Geri should call them. If there's no answer, and the company has gone out of business, she should contact her credit card company and get them to charge it back. She may have been scammed.
