Adobe Acrobat DC \ Microsoft Word I get a Security Warning Certificate Expirer.

Hello Adobe,

I am using Adobe Acrobat DC and when I open Microsoft Word I get a Security Warning. I check the certificate expiration and I see : 10/19/2011 (See Picture Below)

How can I get this issue resolve since this is happening all the time. Why is this add-in not on the Trusted Publisher.

do you have a new Certificate availably for me to download?

Thanks!
