Hello,
first of all, seeing the sparsebundles does not necessarily mean that you see the sparsebundles containing your data.
With later versions of Espionage, we introduced fake sparsebundle images for increased security, the number and size was chosen during initial setup, so no matter we see 2 or 10, these can still all be fake images.
Second, each sparsebundle disk images is given a random, Espionage generated, very strong password, and this one is stored in the encrypted database3 file, which you can unlock with your master password.
So without a database3 file, showing your folders, we cannot do anything, as we are missing the passwords to open the disk images directly.
As Greg said, what you can do is replace the current database3 file with an older one and relaunch Espionage, if the folders are there then we can move on.
If there are no database3 files showing your folders inside the backup folder then the only way to grab them is from your own personal backup if you have any.
So far we did not get any report saying that the folders go missing, so I'm not sure what went wrong in your case. Did you try to restore, or force remove the folders?
If the decryption failed, or you did force removal, then there should be a password text file on your desktop.
Take a look in your trash, once we encrypt the folder, we do not delete the original, instead we put it into the trash. If you did not empty the trash, then the folder might still be there.
