I have the same problem on my kobo Arc 7. hope someone can help us
I'm having the same issue, in ADE it says my Kobo is authorized, on the Kobo it says the file is not authorized.
Here’s a solution to our problem. I received this from our County library download service and it worked for me.
Hi Len, where is the solution?
The solution was an attachment but this time I have copied it below. As I said, it worked for me.
Hello Rosemary Lewis,
Thank you for contacting OverDrive.
This issue can crop up when you're trying to transfer an eBook to your Kobo. We're sorry you're having trouble, but this article should help you out.
Before you try anything below, make sure you're using <http://www.adobe.com/products/digital-editions.html> Adobe Digital Editions (ADE) to transfer eBooks to your Kobo. If you've been trying to use the Kobo desktop software, that could be what's causing the hiccup.
What to try first
Most of the time, simply resetting your Adobe authorization for your Kobo will fix the problem.
1. Make sure the date and time settings on your eBook reader are correct.
You should find these in the Settings menu on your device.
2. Plug your Kobo into your computer with the USB cable that came with your device.
3. Open ADE on your computer.
4. Remove the eBook causing trouble from your library.
5. Click on your device from the menu on the left.
6. Click the Device Options button (shaped like a gear), then select Erase Device Authorization. Click Erase Authorization, then OK to confirm.
7. Try downloading and transferring the title again.
If you're still having trouble, try a factory reset
If resetting your authorization didn't work, you likely need to perform a factory reset on your device. Please remember, when you do this, all of the information you have stored on your device is erased. So, to avoid data loss, make sure you back up anything you don't want to lose.
1. Repeat Steps 1 through 6 above.
2. Close ADE and unplug your Kobo.
As stated above, you will lose all of your data. When you sync next, your eBooks should automatically be restored, but please remember to back everything up before performing the reset.
4. Plug your Kobo back into your computer, then open ADE.
5. Try downloading and transferring the title again.
If there are any more problems, please don't hesitate to reply.

I am having the same problem with my Kobo Aura. I followed all the steps above a number of times and I still can't open my book on my eReader. It's there but when I try to open it the following message comes up
"Oops! This document couldn't be opened. This document is protected by Adobe Digital Rights Management and is not currently authorized for the use with your Adobe ID. Please sign in with the authorized Adobe ID and try again"
I have gone into my readers settings and verified that my Adobe account is authorized.
I don't know what to do!!!
Any help would be much appreciated
After numerous hours trying many steps of loading,deleting, factory default setting ,authorizing and de-authorizing the computer and the Kobo, as recommended by Overdrive and Kobo, I am still unable to download a book from the library, the message reads " this document is protected by Adobe DRM". As a test I purchased a book from Kobo of course this worked great!!!!!! I have given up on Kobo and went back to my Nook, no problems. Considering the stiff price I paid for my Kobo I am still open for a solution,
