I can't remember / find my serial number!

Hi there,

I bought CS5 Design Premium (for Students and Teachers) at the end of 2010 and only loaded it onto one computer. Now, 4 years later, I want to load it on my new computer. The problem: I used an email address to create my Adobe ID that I no longer have access to. I can't even remember the password!

I have the case number written down from when I originally requested my serial number and another 9 digit number (it must be needed with the case number) - would I be able to get my serial number from Adobe support? (I am currently sitting on the chat waiting for an answer but it's taking a while and I was wondering if some kind soul could give me advice )

Thank you!
