This is information You need to know when using ref's program.
When exporting from a ZHF to the RAW format the program adds 4 bytes to the start of the file! Tthey can easily be removed when opening the RAW in PhotoShop!
Failure to do this pushes all pixels 4 places out of place and can and probably will cause CTDs when transformed back to ZHF!
Images below show the proper settings.
