I can't open my library books. I checked the forum and it was suggested that I unauthorize and reauthorize. I did that - I still got the error message that the content was protected by Adobe - I deleted my adobe program and opened a different version, 3.0, that didn't work either. Now I have a new message - check activation. I can't even download books. I am getting pretty disgusted. Getting help is ridiculous - I would rather pay for a service and get some service than go through this.
