Yes, you can upgrade to Axiom from Re-Guitar - just go to your Re-Guitar download page (link received by email upon purchase), and you should see a link to upgrade at the top (you may have to refresh the page if you have been there recently).Any chance of an upgrade path to Axiom full for Re-guitar owners? Starting to wish I just purchased Axiom from the get go.
