Perfect. Now we need to replace the current Library/Application Support/com.taoeffect.Espionage3 folder with the one you found.
Quit espionage
Hold down the option key, and from the Finder's go menu, select Library, this will take you into the appropriate library folder. Now go to application support, and rename the com.taoeffect.Espionage3 folder to something else, and put the one you found into the same folder
Launch Espionage and the folders should be listed.
Now depending on changed paths, if you try to unlock a folder it might complain that the mountpoint folder is missing.
If this happens, create an empty folder using Finder with appropriate name and in appropriate location. Now click onto a small "i" near the folder name in the Espionage folder list and in the folder option window use the mountpoint drop down menu to point Espionage to the newly created folder.
Now with the mountpoint problem fixed, it might complain that the disk image is missing, at the same window in Espionage there will be another drop down menu named Disk image, note the current disk image name, then use the drop down menu to point Espionage to the same disk image but in the new location.
After this all should start to work
Let me know how it went,
