Activation & License

System activation is required on first use. Activation binds license status to the server device identity.

Purpose

• Validate license status and keep service available.
• Support license updates and explicit error feedback.

Entry Paths

• Web: after login, unactivated instances are redirected to activation automatically; users can also open activation updates from Profile.
• H5: same behavior as Web.

Core Flow

1. Open the activation page and copy the Server ID shown on the page.
2. Prepare an activation code:
   • Already have one: enter it directly.
   • Do not have one: contact the author on WeChat Yay_ls to ask about and purchase a license. After payment, submit the Server ID to receive an activation code.
3. Enter the activation code on the activation page and submit.
4. After successful activation, the app redirects to the home page. If activation fails, follow the error message.

Notes & Limits

• Activation codes are device-bound. Use the code on the intended server.
• Server ID and activation code are different fields. Do not paste the Server ID into the activation-code input.
• If activation fails, verify network connectivity and code validity.

Moving to a New Server

To move an existing license to a new server, use License Transfer. It submits a license rebinding request through an encrypted .lltf file and does not move libraries, audio files, or user data.
