D-Link DIR-655 :: Router Configuration File Format Difference Between Rev A And Rev B

I've owned the Rev A DIR-655 for years and have loved it, but recently it started acting up. I have a complicated setup saved as a gateway settings file (.gws).  I decided to purchase a new DIR-655 for the ease of importing my settings without having to manually setup again, however, much to my dismay, the new file format for the configuration settings on the Rev B is not .gws but rather .bin.  The .gws file will not import. I tried changing the file extension to .bin with hopes it might import but no luck. I also found the utility which decrypts the .gws file into .xml and used those values to manually re-enter the settings into the Rev B router, but my port forwarding is not working the same.  I was wondering if there is any utility to convert the .gws file to the .bin file in order to import into the Rev B router, or if not, can I still purchase the Rev A model somewhere. The online shops I've checked do not list the hardware version.
