I have been trying to process some thermal imagery in Pix4D but the initial processing keeps failing due to the following error - ‘no calibrated cameras’. I am using version 4.0.25. I have a colleague who has version 4.2.27 in which the same images will process without error. My subscription has expired so I am unable to update to this version without renewing my license but presumably things should not just stop working in one version when a newer version comes out. Please can you advise?
