John and Michael exchanged worried glances. They had no idea what the code was or where to find it.

The problem was, John's computer had been recently upgraded, and the hardware ID had changed. The validation code, which had been generated for the old hardware, no longer worked.

As they chatted, John's computer beeped, signaling that his EPLAN Electric P8 2019 software was ready to launch. He clicked on the icon, and the program opened, displaying a login screen.

"Enter your validation code," the screen prompted.

John nodded in agreement. "Yeah, and it's not like EPLAN is trying to lock us out. They just want to make sure their software is being used legitimately."
