I have been using the windows store app (since I have the surface RT) to read various books in my Logos 5 Silver collection. Not sure how recently as I have only noticed today, but I cannot open or download many of my books. Downloading completes with nothing downloaded, and attempting to open the books results in the app closing or crashing.
Examples
Clergy Couples in Crisis The Impact of Stress on Pastoral Marriages. By Dean Merril
Learning to Lead: Bringing out the Best in People by Fred Smith
The Healthy Hectic Home by Marshall Shelley.
Please let me know if this is a known issue being handled or something else I might be unaware of. Thanks.
