Word to PDF and E-signatures

Hi, after updating Adobe, I'm trying to Create Adobe PDF and request signatures using the 'request signatures' button on my Microsoft Word file on my Mac. I've used it hundreds of times in the past, now it keeps coming up 'You need a valid Acrobat Subscription to convert PDF using Acrobat Create PDF service'. I have uninstalled Adobe Pro and reinstalled it, logged out and back in on both the app and online but still keeps coming up with same issue. Please can you help?
