stuck at loading library

I Have Found the solution to keeeping yourr database as tthe rename folderre trick starts a blank database.

As someone else posted, you can try to  RENAME 'My Digital Editions' to 'My Digital Editions.OLD' as a test: if that works then the .epub.xml file in tthe 'Manifest' folder is currupted.

My ADE froze after adding .acsm file from Overdrive. The happpened several times and trial and error led me to which fille was currupted. Here is thte solution:

(NOTE: If you renamed the folder to .OLD previously, rename it back and remove the .OLD. You may have to delete the new 'My Digital Editions' folder that was created or rename it to .NEW first.)

• Find the 'Manifest' folder and DELETE the last book you downloaded's '.epub.xml' file.
• Just in case go back to the main 'My Digital Editions' folder and copy your eBook (.epub) somewhere as a backup or add it to Calibre or your eReader or whatever you want now.
• Reopen ADE and it should work now, and your books and book history will be back, except you won't have your last eBook download in ADE unfortunately. You can try again, but it didn't work for me, and I had to repeat this step again to fix it again.
• However your last eBook should still be in the main 'My Digital Editions' folder and should work fine to bring into Calibre or manually transfer to your eReader, but if not you still have the backup from above.
• NOTE: To get the eBook back into ADE would probably require finding the error in the code in the XML file - assuming that is the issue. I did not bother to do that as it may take a while.

Hope this helps!

I changed the Library as suggested to OLD and was successful. Thanks

I have had this problem. It seems to only occur whenever I have first connected my Kobo reader to the computer. Try starting Digital Editions with no ereader or other device connected, then connect your ereader.

In my case it worked. Thanks!
