Legacy Adobe Acrobat XI Standard - Account Issues to Deactivate a Device

I have a old (legacy) version of Adobe Acrobat XI Standard which was loaded originally via a CD.  Apparently I have more than two (2) installs on my different devices.  I keep getting an error notification stating I need to deactivate at least one device the software is installed on.  However, when I log into the two (2) only possible emails I have with Adobe to deactivate the hardware, both log ins show ZERO activations on anything and I can't re-register the original key or find where they have this Adobe key attached to what email.  And totally no support whatsoever from Adobe when I try their chat or contact.
