I'm trying to borrow books from the local library. Whenever I select a book to borrow, I then select to open the file. Adobe reader does not read file and ansers that it is not a supported file type, or the file has been damaged, e.g., email attachment that has not correctly decoded. This happens with any book or publisher. I have reloaded digital editions, I have renewed my authorization for my computer, I have reloaded and completed maintenance on the reader to no avail. Frustrated?
