sign out and then back in to your cc desktop application using the same adobe id used to pay for your subscription: http://helpx.adobe.com/creative-cloud/kb/sign-in-out-creative-cloud-desktop-app.html
if the problem continues,
Where can i see the id i used to buy the subscription?
I can not see the membership in my acount
if your account, Adobe ID does not show your subscription, you either are using the wrong id or you don't have a subscription.
do you have an email received from adobe confirming your subscription? that email address is your adobe id.
