There should be a command on your instrument that allows it to dump its settings via SysEx. Start the capture application recording and then push the appropriate button on your synthesizer to transmit the SysEx data. Stop recording in the application when the dump is complete. Now save that file as a MIDI file. When your synth next loses its mind (which I pray doesn't happen again), just reload its setups and sounds from this file.
Note: You don't need to dash out and purchase an expensive DAW application to do this. SysEx Librarian is a free utility that can both capture and transmit SysEx data. I recently used it to install a firmware update on my Kurzweil PC2X synthesizer (and then backed up my performance settings from that keyboard to my Mac).
