Hi,

Thank you for posting your query here.

Please share brief details about your Creative Cloud Subscription as well as the Windows Operating system and the OS Build version, in order to be able to assist in a better way as this is user forums and we do not have access to your Subscription details.

If issue persists, 

You may contact Support Team by clicking on : https://helpx.adobe.com/contact/support.html for chat or https://helpx.adobe.com/contact/phone.html
-click the chat icon at the bottom right of the page to open a chat session
-the chat icon looks like '3 dots inside a circle' at the lower right
-type AGENT into the chat window to connect directly to a person rather than the AI

Hope this helps. 

Also which version of Windows?
