I try to open an e book in ADE and get a message that says "error check activation". How do I fix this? Never had this problem before.

I get the same message when I attempt to transfer an eBook from my local library which is in my computer, to Adobe Digital Editions.

I went on to "chat" but they are not experts in this field so they directed me to this forum.  I am really disappointed.  I am not a novice at this.  I had 2 Kobo Glo eReaders working without problems.  Now I have one broken eReader and another that I can't transfer eBooks to.  I can buy books from Kobo - no problem.

Same problem all of a sudden. In the help section it says to erase authorization and re-authorize. I tried but when I go to erase it said "unable to erase authorization. please try some time later". I have been trying for three days. I tried to chat Adobe today, after 20 minutes of being passed around they said that Digital Editions does not support live chat. I'm looking for any help out there.
