I can no longer read my very expensive eBook via Adobe Digital Editions
I can no longer read my eBook and I get errors when trying to reauthorize my computer. I need help.
Normally I just double click on the book and it pops up. Now I am getting the following:

On the next screen, when I enter in my adobe ID and password, I get an error:

However, this is ABSOLUTELY my adobe ID and password. I just double checked and was able to log into Adobe.com with it. I tried to select a different vendor, but it won't let me. So then I canceled the whole process and tried going about it a different way.
I went to the "Help" screen and selected "Authorize Computer..." Which pulled up this:

This was a weird message to see, becasue I was pretty sure that this computer was already authorized. I decided to continue anyway which took me to the next screen where it once again asked for adobe ID and password. When I clicked "Authorize", I got the following:

What does that mean and how do I fix it? I tried going through Adobe chat and they said the only help available is through these forums and to hope an expert sees this.
I spent a lot of money on the eBook and I'm using it for an important research project. I seriously do not want to have to purchase it again if I don't have to.
Help would be greatly appreciated.
