Acrobat 2 is a very old unsupported version.
Good day Andy,
It sounds like the Acrobat.com Desktop Applicaiton is trying to update. Unfortunately that update doesn't exist anymore and the Acrobat.com Desktop Application is no longer supported. I'd recommend uninstalling that application from your system. To access Acrobat.com moving forward, visit http://acrobat.com/signin.html
