pop-up blocking screen that asks if I would like to get free 7 day trial (already paid subsription)

Hi there

Hope you are doing well and sorry for the trouble. AS described you are getting the pop-up screen for 7 day trial

Please logout of the application, reboot the computer once and relogin with the same Adobe ID/Email and check if that helps.

Also, make sure you are using Adobe Acrobat DC application and not the Adobe Acrobat Reader DC (Freeware application).

If the previous solutions do not work, your computer could have trouble connecting to Adobe's activation servers. This could be because of an incorrectly configured Operating System hosts file (Operating system hosts files map host names to IP addresses).

To solve this issue, try removing Adobe-related entries from the hosts file. You can remove the Adobe-related entries from the hosts file in two ways:

Automatically repair the hosts file using the Limited Access Repair tool: Repair the hosts file using the Limited Access Repair tool. With this method, you do not have to manually edit the hosts file -- the tool automatically repairs the file. 

Reset the hosts file manually: If the issue is not fixed even after you run the Limited Access Repair tool, reset the hosts file manually.

If the solutions above are not working, try the steps in Resolve connection errors.

Regards

Amal
