Yeah, sorry I cannot help. It is a little bit of a different problem than mine. I can access the reader from my desktop but my reader just will not show up in the eBook Library software. Instead of saying Reader, it says Error.
You might try giving the customer service people a call. They have a specific number for eBook issues. Just look at this website (scroll down to find the phone number):
