License Troubleshooting
Common Issues
Section titled “Common Issues”"License Invalid" After Hardware Change
Section titled “"License Invalid" After Hardware Change”Your license is bound to your hardware fingerprint. If you changed your motherboard or CPU, the fingerprint no longer matches. Follow Transferring to Another PC to move the activation — or contact support if the old machine is no longer available to deactivate.
License Not Refreshing
Section titled “License Not Refreshing”If MZAP can't reach the activation server, check your internet connection and firewall settings.
Grace Period
Section titled “Grace Period”If the license server is unreachable, MZAP enters a grace period and keeps playing normally. Reconnect to the internet before the grace period ends — once MZAP reaches the server again, the grace period clears automatically.
