[chirp_users] FT-817 Clone Rx error

I've used Chrip sucessfully with a Baofeng for a while, but I'm running in to issues with my F-817.

I've recieved an image ok from the radio buy putting into clone mode hitting a and downloading the image. I've then edited the image. As soon as I press the C button on the radio for upload it just says "CLONE MODE" "Error" .

Has anyone else had the same issue?

Thanks
