I have version 5.3.122. I didn’t work with Ctrlr for quite awhile but I seem to remember I did stick with this version exactly because of the background image problem. I did a quick check if this version does load a background and it did. No 100% guarantee of course;-). I can send you the program file using WeTransfer, but I’m not sure if that is all you need. I don’t have the original instal folder. Just let me know.
