My apologies for a slightly delayed reply. (Sunday nights are a particularly busy time for support for us.) Could you clarify?:
Hence I exported the config file
By that, do you mean that you just made a copy/backup of the OrganIDNNNNNNConfig.OrganConfig_Hauptwerk_xml file itself manually (e.g. using Windows Explorer)?

Do you mean that you had made some changes with your CODM ODF and then re-loaded it using 'Design tools | Load custom organ'?
If so, had you changed the OrganID in the ODF (which would make it appear to be a completely separate organ to Hauptwerk, with completely independent settings and voicing), and/or had you changed any of the RankIDs? (The latter would be likely to invalidate/reset any voicing.)
Also, when you loaded the organ, had you used any of the reset options on the design options screen?
Or are you referring to having made some changed manually in a full-format ODF (as opposed to a CODM ODF)?

By that do you mean that you just copied your previously-saved OrganIDNNNNNNConfig.OrganConfig_Hauptwerk_xml file back into Config0-OrganSettings folder (e.g. using Windows Explorer), replacing the file that was previously there (which would presumably have been the same file)?
Or do you mean that you tried to make some edits manually (e.g. with a text/XML editor) within the OrganIDNNNNNNConfig.OrganConfig_Hauptwerk_xml file? Or perhaps that you had changed the OrganID in your ODF, so you had tried to change the name of the OrganIDNNNNNNConfig.OrganConfig_Hauptwerk_xml file to reflect the new OrganID number?
(Trying to make any edits manually within the organ-configuration files definitely isn't supported, I'm afraid -- they're internal to Hauptwerk, and undocumented.)
