Using Espionage with an External Hard Drive

I made a data encryption file (.sparsebundle file) in an external hard drive by using Espionage.
And I reset my mac with clean-installing OS X and installed same version of Espionage.
But I don't know how to restore the encrypted file in the external hard drive in this new system. Could anyone give an advice?
PLZ..
