No, there is no button or link to activate, only request to Renew Subscription on the message window with a link to the login webpage. When I login, it takes me to the Plan Information page.
There I see two Creative Cloud panels: one for Free membership with the account status telling me I have access to 30 day trials and one for CC membership (one year). There is no button or link to activate. Based on the phone conversation I had with the Billing person, she activated it for me after I gave her my credit card information (which is the same I entered online when I received the new card).
Can I go ahead and close the Free membership one? I was going to but was afraid it would also cancel the CC one year membership.
What next???? I need to use the apps. This is holding my projects back.
