Thanks, you're right the rest was cut off. Neither the ProjectFiles or QueueFiles directories existed. I wouldn't have thought to create those or get ImgBurn to use those. ImgBurn created subfolders for Graph Data Files and Log Files. Unless some other program is misbehaving it seems either ImgBurn tried and failed to create the missing dirs or just didn't try but set the paths as such anyway. I really don't think I deleted those folders. Thanks also to blutach's suggestion the problem is resolved for me
