If you restart it, it should pick up where it left off.
I have not figured how to restart it.
Just relaunch the Media Downloader. You would see a short cut icon on the desktop to launch it again,
Icon is on desktop. While it opens and shows archiving in process, no files are added to the folder.
If I go to the Adobe site, it asks me to download the downloader and then shows in the same download in progress window that is not true. UGH!
Are you downloading to an external drive or to your main hard drive? Granted as long as you have the latest Adobe air installed http://get.adobe.com/air/
then you should be fine.Then try clicking on this to install it again http://www.photoshop.com/misc/membership-faq#downloader
Let us know how if you are still having this problem
I have verified that I have the current Adobe Air.
I have uninstalled and reinstalled the downloader and it still shows that downloading is in process, but no download occurs.
Are you using Mac or PC? Also do you have any external drives connected to your computer? Is the problem still occuring? I thought I would follow up to get an update from you?
