# Not Authorized

If you receive the error **"You are not authorized to use this account"**, it means your current **Hardware ID (HWID)** does not match the unique ID recorded when you first successfully logged into the loader.

<Note>
  **First-Time Usage**

  Even if this is the very first time you are using our product, this error can appear due to an initial issue. The fix requires opening a support ticket.
</Note>

## HWID Troubleshooting

Your HWID is a unique key derived from your PC's components (CPU, Motherboard, storage devices, etc.). The loader is tied to this key.

<Steps>
  <Step title="Check for Hardware Changes">
    Think back to when you last successfully used the loader. Did you make any changes since then?

    * **Monitors:** Did you disable, enable, or swap a monitor?
    * **Storage:** Did you add or remove an SSD or HDD?
    * **USB Devices:** Did you add or remove any permanent USB drive?
    * **VPN:** Did you enable a VPN?

    Even minor changes can alter your HWID.
  </Step>

  <Step title="Open a HWID Reset Ticket">
    If you did make any changes to your PC's hardware configuration, your HWID is different. You will need to request a reset.

  <Step title="Verify Loader Download Source">
    If someone sent you the loader executable directly (e.g., via Discord or email), it might be corrupted or outdated.
