Yamaha Music ID was recently updated, and in some cases, previously stored browser data can interfere with the new version. Most issues of this nature are resolved by completing the following steps:

1. Clear your browser’s cache, cookies, and history.
2. Fully close the browser (all windows), then reopen it and try again.
3. If the issue persists, please try accessing Yamaha Music ID using a different browser (for example, Chrome, Safari, Edge, or Firefox).

These steps typically resolve account access errors following system updates. You should then be able to register your eligible Yamaha keyboard.
