You could have a software firewall which is interferring if you are home user. If you are on a corporate network then you may also want to try working with your I.T. department. Have you tried hooking your computer up to a different Internet connection and seeing if the problem continues?
I am a home user that uses FTTH with a wireless router.
I first tried it from each of my 3 computers through the router with its firewall turned off, then directly connected one of them without the router, but to no avail. The results were the same.
For testing, I reconnected my computer to the router and turned the firewall back on, and then tried downloading Adobe Premiere Elements 10 trial.
It asked for my Adobe ID, and I entered it. Then the download successfully started and completed.
I could still try another network when I have a chance, but from the above result, plus the fact that I usually don’t have any network problem, I hardly think my home network is the problem.
I wonder why I specifically can’t activate Story. Any idea?
Well I checked the status of Adobe Story again and it is up and running and fully functional. I would recommend for your next step to contact our support team and if they can't resolve the issue work with your Internet Service Provider.
