I just got a Muse. Yay! I went to register it and it looks like my old pre-InMusic login no longer exists so I created an InMusic account and tried to register but it’s telling me I need a 30 character serial code. I only have a 17-character serial code that starts with 21. I tried following [these instructions](https://forum.moogmusic.com/t/want-to-update-firmware-but-my-muse-wont-register/23288) and it takes me to the same place and the help chat on the site tells me the same thing. What am I missing?

That said, I found a couple preset packs and the 1.4 firmware already. Is there anything else available to me after I register?

The Muse does have a 17 character serial code starting with 21. You should contact customer service.
