Invalid reinstall,Computer restart is invalid.
Is this a new installation or Freedome VPN had been working fine until now? You may want to try to reinstall the program while checking that your Windows Updates are cleared.
If the issue persists, try to disable any anti-virus program or conflicting software like another VPN service on your computer before trying to activate the Freedome subscription.
If it persists, try to change the Internet connection to either mobile hotspot or other available wifi and see if that works.
