License Error

[Guest]

I have two books purchased and functioning fine thru Adobe Digital Editions.  For no apparent reason one of the books will no longer launch and the errors are below:

Document is not licensed for this device type
Document is not licensed for this machine

I have not changed the pc or the program...one continues to function the other does not.

I have had two poor experiences with tech support...any help would be appreciated.

Hello,

I am having a similar problem. I purchased an e-book through a1books.com thinking that this will be a very convenient way for me to read this book as long as I had computer and Internet access.

I do not have my own computer and am at my school's library all day every day, and on different computers. I was asked to install Digital Editions and then to download the book this way. After having downloaded it to my brother's laptop last week, I am now on my own at a library, and I have installed Digital Editions on here, but cannot view my book!

I don't know how to view it! This is so ridiculous, why is it so hard to access something that I paid money for?!

Is there any help with this issue? The error I  am getting is that the license is already in use or something of the sort, but I am the owner of the license!

Thanks in advance.
