When you scan a book and the program reads IO Exception. It means either your SD card is defective or you did not download database properly.

To troubleshoot, please follow the steps below:

  1. If you follow our Multiple SD cards recommendations, you can immediately try with your another card loaded with older database.
  2. If you do not have a backup SD card, you need to go home and find a different SD card to download database. Make sure you setup your SD card.
  3. If there is no IO Exception on your new card and you can scan items properly. Then your old card is defective and needs to be thrown away.
  4. If there is still an IO Exception, then contact us so you can try with a different PDA.
