Matthew I'm sorry to hear you're having trouble.
i tried latest versions first and actully downgraded to lower versions..anyone know whats up?
Did you use Spine 4.1 and selected 3.8 in the export settings when exporting in JSON format? If so, that skeleton data cannot be imported successfully in spine-unity 3.8. Please note that the Version option for JSON export is only for use if you want to downgrade your Spine project. The major and minor version for the Spine editor used to export JSON or binary data must always match the Spine Runtimes version. If you would like to create animations using Spine 4.1, please upgrade the spine-unity runtime in your Unity project to 4.1.
If my assumptions above do not match your issue, I would appreciate it if you describe it in more detail.
