I'm using DPP to edit my raw files and trying to use the dropper tool to set white balance on a raw image. I am able to do all this just fine but when I try to register the white balance setting for use on another image, DPP returns an error 'cannot write file'. There are only 3 custom settings (1,2,3) so its not like there is an incorrect file name. Has anyone seen this problem or is there a required directory that needs to be set up for DPP to be able to 'register' the custom white balance setting?


Thanks in advance for you help
