What are the steps to update this information. I am attempting to upgrade to Version 6 and I'm afraid we won't be communicated with at the right email address.
When you purchase the new v6 upgrade, simply use your new/preferred email address and it will be reflected in the new license sent to you. Your older license however must continue to use the old email address. This email is not used for communications however, but simply to generate a random license number, so it should not be a problem.
