This is an ongoing issue for me. Whether it's AAM or the new CCM, when I attempt to access apps and updates I receive a Download Error message (see pic) which will not allow me to update or download apps.
After experiencing this with the AAM in May, Adobe support provided me with a work around which amounted to creating a new user on my machine and installing the AAM for that user. I was then able to update the apps I'd installed previously and install two more apps on my machine.
Now I'm experiencing this issue again - still for the default user on my machine and now for the new fake user I created per Adobe support's instructions.
I'm using Windows 8, Google Chrome browser (I can't update the apps through Adobe, either).
I'd love to get a handle on this issue and get it corrected once and for all and, hopefully, without having to create another 'ghost' user so I can update and install apps.
Thanks.
