500 Internal Server Error accessing content server Calibre 0.8.8

I was hoping that someone could help me interpret this error message-

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Initially I synced my Ziio 7" to my desktop that is running Firefox 1.0 for Linux Mint using an earlier build of Calibre that would not allow me to add books to my library (the first time I have ever experienced a problem with Calibre). When I checked my package manager, I found that Calibre 0.8.8 was available and installed that version correcting the error regarding adding books. I don't remember if I was still able to access the content server at that point.

At this time I tried to sync a 2nd ZiiO, a 10 inch version and that is when I found that I could not access the content server. The same problem occurred when I tried accessing using the other ZiiO.

I am including the error log for today-

If anyone could help me out with this I would sure appreciate it. I can still connect witht he USB cable but it sure was fun to be able to sit in my recliner and access books from my computer downstairs.

Hold the bus!

I checked out the calibre download page and saw the notice about not using your distro's latest build, so I downloaded the most current version from calibre's website and installed it and it is working fine...including adding books to my library!!!! I did have to remove the password for it to work.
