I previously had 1.7 version installed on my desktop and the available app installed on my iPhone 5. I was able to upload AxCrypt files to my iPhone and read the files. I was able to maintain the app on my iPhone even though the App Store withdrew the app. When I upgraded my desktop version to 2.0 everything worked okay on desktop and even though I could upload files to my iPhone I could open the files with the existing app. Can I reinstall the previous 1.7 version and operate as before until a new app is released that will work with version 2.0.
