Hi @patrick.oneill-7283, this sounds like Lightroom may be using the wrong version of our plugin – please try downloading a new copy of the Photo AI installer from this download link here and use it to repair/overwrite your current installation.
Make sure Lightroom is closed when you run this installer again.
After this, try your plugin once more and please let me know if this behavior stays the same.
If the above is not the issue, please send me the CR2 file so I can check if it’s supported. You can securely submit your image(s) to my Dropbox using the link below. Please be sure to send me a note to let me know you sent something. Dropbox File Request
