Registration says supports@zoominternet.net already taken

We have purchased Adobe Acrobat Pro from a company called Tech Soup. We are a non profit agency so we could purchase at a reduced price.

Originally we had a copy of AAP installed on another computer here in our office but needed to uninstall it so we could use the install on a new computer.

After installing on our new computer the registration keeps saying supports@zoominternet.net is already used.

How can I get around this issue?

thank you.
