Two things: 1) Even though I've subscribed to Pro DC I consistently get a message indicating I'm not subscribed. 2) How can I create a document with questions so that the answers are fillable?
We apologize for the inconvenience caused, as per the description above, you are getting a message to resubscribe Acrobat Pro DC, and you want to create a fillable PDF form, Is that correct?
The record shows that you are subscribed to Acrobat Pro DC subscription on your current Adobe ID. If Acrobat Pro DC is installed on your computer, then sign out and sign back in with your current Adobe ID and password in Acrobat and see if this removes the error message.
To download Acrobat Pro DC, use the URL Download Pro or Standard versions of Acrobat DC, 2017, XI, or X
