Well,
You may have other options.If you have a old backup you can use it like I said before. You just will need to update it after uploading.
Another option is if you have the original zip file, set up a test board and let it create a new config file and copy it over to the live board.
Or somebody may have a default config file for you to use. But you need to let us know what the version is. Also Rick could rebuild your config file. If you open a support ticket.
