How to upgrade to AnyDVD HD from AnyDVD without the e-mail address used from original purchase?

I currently have AnyDVD and someone had purchased it for me. I want to upgrade to AnyDVD HD & on the SlySoft website it asks for the e-mail address from the original purchase. What do I do if I do not have this?

Contact Slysoft and ask them what to do about it. As long as they can confirm your licence I imagine there shouldn’t be a problem.

You need to contact Slysoft directly. They have a form to fill out when you have a purchase problem:

When they respond, they may want you to send a copy of your current key, and details of who purchased it originally, even if you cannot provide the original email address.
