New computer, iBooks won't download

I purchased a new computer and authorized it to my iTunes account. When I open iBooks, all my book titles appear, showing they are in the Cloud. When I downloaded a book from the cloud and it states:

"This page contains the following errors:

error on line 1 at column 1: Encoding error

Below is a rendering of the page up to the first error.

No pages appear. I've tried to open multiple books I've purchased but all are downloaded from the cloud with this same message. How do I solve this?
