I have an ipad2 running version 4.3.2 with 64gb of memory. App has worked fine until yesterday when I tried to download the NIB which was released on Thursday. The app will open but then it freezes when I try to search my library. I have deleted the app and restarted my ipad a number of times, with the same results. at the present, it wants me to download "Missing Books". When I tap on download, the library comes up. I try to search and it freezes again. I have even left it running all night but no success. Any thoughts or suggestions???
