How do I re-download Acrobat Pro?

[sylvioc14533789]

In 2014, I purchased, downloaded and installed Adobe Acrobat XI Pro Student and Teacher Edition.  Back in November, my MacBook Pro was stolen, and I restored my stuff onto a new MacBook Air.  I just tried to open Acrobat, and I was instructed to uninstall and reinstall (“Error 1”).  Having uninstalled, I want to re-download my purchase.  How do I do that?

Just tried it, and was told "invalid serial number."  Tried without dashes and got the same response.
