Don't know if this helps: Downloaded a crashed runtime from the iPad to my MAC. Tried to run recovery. but the file cannot be selected. In the runtime "Admin Access" was removed on purpose in creation of riuntime. Double clicked the damaged runtimre to open and received the following mesage: The translator for this file format could not be found or could not be initialized.
Trashed the offending file, fortuneltly, continued working with a previous version. Also rebooted the iPad. Twice before have fixed issues with FM Go by rebooting iPad.
