Okay, as a test, I found a book that had the option to borrow from overdrive from the device. I tried to borrow, and I got the "there seems to be a problem" error. So, it seems that I'm able to put books on hold from the device (I've done that a few times), but as far as I can tell, I can't seem to actually borrow anything from the device or download something that I borrowed elsewhere?
EDIT: so, I went to my library website, and it looks like I did actually check out the book from the device. It is showing as checked out according to my library website. Go figure.
Now how to get the book to actually come to my device.
