After a less than pleasant experience installing ADE 4.5.10, I clicked on the link for the ebook provided by the bookshop and the book appeared to download and was listed in the library. However when attenpting to view the book, found that only the front cover was displayed and the remaining 186 pages were blank. Have left thsi for a few hour now in case there was still content in transit, and have also restarted everything, but no change in result. Have also dowloaded a sample ebook ( sherlock adventures) and can see all content. All thsi is happening on a w Windows 10 Surface. Whats the go?
