Your license key is locked to your computer’s hardware ID (HWID).
You must reset your HWID if you:
Factory reset your PC
Used your key on Natural Spoofer and now want to use Kernel Spoofer
Used Kernel Spoofer and want to switch back to Natural Spoofer
Resetting the HWID unlocks your license so it can be used again on a different spoofer or after a factory reset.
