Book download issue: E_LIC_USER_UNKNOWN

The following has been emailed to PE/EE owners. Reproduced here for reference.

Dear Valued Customer:
Due to a recent server modification by one of our content providers, you may encounter the following error when attempting to download purchased e-books: E_LIC_USER_UNKNOWN. This error string is displayed in the notification bar at the top of the tablet screen and can be viewed by pulling down the bar.

We are working with our content provider to rectify this issue. In the meantime we have provided a small downloadable application that you’ll need to execute just once to update your device. Without this workaround, you may not be able to download purchased e-books. Here are the steps you will need to follow:

STEP 1: DOWNLOAD
Download directly to your eDGe by opening your eDGe browser and typing in the following address string:
http://www.entourageedge.com/support...kDownloads.apk.
The download should begin immediately and takes just a few seconds to complete. [NOTE: Your eDGe must be connected to the internet.]

Optionally: Download to a PC by opening your PC browser and typing in the following address string:
http://www.entourageedge.com/support...kDownloads.apk.
The download should begin immediately and takes just a few seconds to complete. Copy the downloaded file to your eDGe using the miniUSB cable or a USB storage device. For detailed instructions on copying files to your eDGe, see this article:
https://www.entourageedge.com/suppor...kbarticleid=83.
[NOTE: Your PC must be connected to the internet.]

STEP 2: INSTALL
Select the file from the download or storage menu and you will be prompted to Install or Cancel. Select Install and the application will be installed on your device.

STEP 3: OPEN
You will be notified that the Application is installed and given the options Open or Done. Select Open to execute the application. You will then be notified that the application needs to modify your activation.xml file, select OK and the process will be complete.

We apologize for any inconvenience and thank you for you patience.

I wonder if this is the fix to the bug I reported? This is the exact same message I reported to tech support several weeks ago and also the same bug that caused all my Adobe ID problems.

I'm guessing yes, Nia. I tried to find that post but wasn't able to. I clearly remembered someone reporting this exact message.

Got that email today also. Nice to see they are still offering support!
