Recently when I started Pleco , it behaved as if the relevant application files were missing and began to download files and rebuild the application. All of my settings, customizations, dictionaries (purchased and user), and flashcards are now missing from the system. Is there anyway to recover these from the files on my phone or SD card, or would those have been overwritten with the rebuild? Unfortunately I do not have recent backups of settings or flashcards. I found two copies of com.pleco.chinesesystem, one on the phone, the other on the SD card; the latter seems to have the pqb files associated with flashcards and user dictionaries that I need. Is that enough? I'm still not sure why the rebuild happened in the first place. Thanks.
