Change Email On Account

We needed to purchase Wirecast in a bit of a crunch. So I put my work email on the account to get the download links etc.

Moving forward, it may be best to put the company owner on the account, especially for any billing/renewal concerns in 12 months. Is there a way I would change that, is it done thru Wirecast or the billing company (2checkout)??

Tried following this form but not sure the link works anymore: https://telestreamforum.forumbee.com/t/g9hx2mj/need-to-update-account-email-address-and-password

Thanks,
