We no longer support or update the Annabelle theme as it is a free resource. It is intended as a resource for developers and users who can customise it to their needs, as we can no longer support it. You'll want to reach out to a Shopify Expert, if you intend to use the theme, or to look for a new theme in the Theme Store.
You may also want to check out the services from Storetasker; the expert pool at Storetasker delivers an exceptional level of service on-demand and could definitely help you with this task - Check them out here.
If you still want to use the theme, unsupported, you can find the files attached here to download.
