I have downloaded and synced from Kobo to my Libre with no problems.
But when I try to download ebooks from the public library they download and open in Digital Editions just fine. I drag and drop them into the bookshelf marked Libre-eBook Reader Pro.
They show up when I turn on my ebook, but when I try to open them I get the 'failed to open the file'.
I was also getting the Error 2038 in Digital Editions when I did the drag and drop thing. I read through the forum and went through the steps recommended for the Nook ~ deleting the digital editions folder on my ebook and having Adobe reauthorize it. I no longer get the 2038 error message in Adobe, but I am still unable to open the books from the library.
I have tried deleting the books from ereader and ADE and redownloading from the Library. Didn't help.
