fort8877 You can only specify the version when exporting in JSON format, but I'm concerned about the mention of “Binary version” in the import dialog. Have you saved the JSON file with the .json extension? If you save it as .skel, Spine may mistakenly recognize it as a binary file instead of a JSON file.
If you have confirmed that you are exporting in JSON format and it still does not work, please send us the skeleton file that is causing the error via email so that we can investigate the issue: contact@esotericsoftware.com
Please include the URL of this forum thread in the email so we know the context. Then we can take a look at what's wrong.
