ERROR: Synchronization cannot be performed because this wallet and destination wallet are not using the same password.

This error means that the wallet file you have set to sync on your desktop does not have the same password as the wallet file with the same name on whatever device you are syncing to. Note: A wallet with no password (like the sample wallet provided with eWallet) actually has a password, but it is hard-coded into eWallet so you never need to enter it.

Make sure both wallet files have identical passwords; passwords are case-sensitive so ensure they are completely identical.
