Whatsapp changed the encryption from CRYPT to CRYP5 (or even CRYPT6 in latest beta), and users might find it difficult to convert these new databases with previously working programs like Whatsapp Xtract.
You can always try http://whatsapp.livetrack.mobi/ online web extraction service, but it might not work on latest databases.
This conversion entry was verified by us and conversion was flagged as wrong or not possible.
Usually this happens when the conversion would try to convert different types of data between each other, such as audio to image, or it is not possible because incompatibility between programs, caused by closed file formats, very limited support etc.
If you find entry that you feel is flagged as bad wrongly, please tell us in the discussion below with as much as information as possible so we can fix it.
