Are you using MapReverseConverter because you're wanting an older version of MS, v6.13.3 or earlier, to handle your maps? If that's not the reason then there is no need to be using MRC just to relocate your GMAP folders. Read this Post 2 [Only registered and activated users can see links. ] as linked above by catymag, or you can just leave shortcuts in the default directory pointing to your maps new location on another drive, also stated above.
