Hi vickib61138142,
I've checked your account using the email that you use here in the forums. It looks like you were last charged $19.99 on December 7 2014 for your Acrobat Pro subscription. And that subscription is now expired due to a payment processing error (maybe the expiration date on your card changed?). According to your records, when were you charged last?
I would recommend that you Contact Customer Care if you're finding that you've been charged in January/February but sill don't have access to your subscription.
You can also update the credit card information stored for you account by following the instructions in this document: Manage your membership and payments | Creative Cloud
Kind regards,
Sara
