Good potential, not stable for me

Ive been using Web Designer Magazine for a while, but only just recently got the Newsstand version of it. Everything downloaded fine, and I have access to all my previous editions, however on the most recent issue release, I cant read the magazine. I had read about half way through before upgrading to the newsstand version, but the version now running in newsstand wont allow me to navigate through any pages. I can open the app, I open the magazine, but then it just freezes on the page its showing and wont navigate. I have to exit the app completely to regain any control.
