Added option to use a default empty Android target db msgstore.db.crypt so that you don't need to get one from your new Android device. Thanks a lot to Mahmoud Nabeel!
Some users reported that recent messages were not transferred. That's because I originally set a hard limit to 70000 messages. Now no limit is enabled so no message is skipped.
Found the way to solve the issue.
Enabled auto-installation of Java Cryptography Extension (JCE) Unlimited Strength. The first time you run WhatsappMigrator you're asked if you want to install it. Please make sure to run WhatsappMigrator as administrator (at least the first time, otherwise it can't install the Java extension).
