REINSTALL ACROBAT XI PRO WITH PRODUCT KEY

I recently had my programs wiped out.  I have my adobe acrobat xi pro product key, but don't know how to reinstall.  I was told to go to "creative.adobe.com" to reinstall the software.  However, the only options at that URL are to get a trial version, a new subscription or to again buy the software.  Where do I go to reinstall the software?
