Need Re-Download, But Can't Do It

I'm stuck in a loop here and if anyone has ideas to help, I'd appreciate it.
Back in 2005, I purchased and downloaded online Dreamweaver. I just bought a
new computer (switched from one Mac to another) and when I transferred the old
Dreamweaver application to the new, I cannot open it on the new machine. I get
an error message that says I need to re-download.

Fortunately, I saved the old email with my purchase confirmation, serial
number, etc., but when I try to re-download, because I've forgotten my Adobe ID
and the email address I used when I purchased the product is now defunct, I
cannot get to the page that lets me re-download. I have a legitimate copy of
Dreamweaver but cannot use it -- and the process to redownload appears
unavailable to me since I changed email addresses. Does anyone know if there's
anything I can do other than call Customer Support?

Thanks!

Well there is one other option. If you have MX 2004 or 8 you can upgrade to
CS4. If you have MX2004 this is actually your last chance to upgrade before
you have a new license so this might be something else to consider.
