I'm reaching out for assistance regarding an issue I'm experiencing with my machine. The screen broke, and I'm trying to reinstall the app. I have the serial number, but the activation code isn't showing up, which is preventing me from logging in properly. I'm really hoping you can guide me through the process or provide any additional support to resolve this issue. Your help would mean a lot to get my machine up and running again. Thanks!
