This happens when using newer camera with older software. Updates happen all the time for software. I'm going to have you update your Adobe Camera Raw Plugin.
Run this: https://helpx.adobe.com/x-productkb/multi/camera-raw-plug-in-installer.htmlThat will make sure you have the latest version of the plugin, and you should be able to open your raw files. Let me know if it gives you any problems.
