Registered to an old e-mail

My license key is registered to an outdated e-mail address. How can I change the e-mail address the key is registered to and how can I change the e-mail address information about updates is sent to?

Hi,

Just email me at nate@natephotographic.com and let me know what email address the license is currently registered to, and what email you’d like it changed to.
