payment

Adobe is the worst thing I've seen in my life! They are thieves, please never buy from them whoever reads this.

They charge you for a whole year even if you retire before and don't allow you to unsuscribed unless you have paid, they basically take your credit card as a hostage.

check your account to verify your subscription is what you expect and to verify your adobe id (used in the next step), https://www.adobe.com/account.html

if your account shows

a. your subscription is active,

1.  sign out and then back in to your cc desktop application using the same adobe id above to verify your subscription:  http://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html

2.  if that fails, https://helpx.adobe.com/creative-cloud/kb/cc-reverts-to-trial.html

if your account shows

b. you have no subscription and you're paying for one

1. using a browser that allows popups and cookies,  contact adobe support during pst business hours by clicking here and, when available, click 'still need help', http://helpx.adobe.com/x-productkb/global/service-ccm.html

What exactly did you purchase? A subscription, or a perpetual license? What version did you install?
