recovering database after re-formatting disk

hi
after experiencing major system problems, I backed up my hard-drive both manually & w/ time-machine, then erased my hard disk and reinstalled macOS10.7.4. Now (in addition to other issues that have also arisen), I can no longer open the database from the "old" files on the previous disk. I managed to copy the scarcebundle file to the new disk, and copied the folder into which espionage 3 opened the disk image; espionage identifies the file, but reports a critical error: could not mount disk, etc. What should I do? Thanks
