I hope the previous comments have resolved the issue of downloading the program to your PC.
In addition, please pay attention to the system version of the software when you modify the program with your PC.
A program cannot be loaded on a system older than the version on which it was built.
For example, if you are using a newer version of software on your PC than the software installed in the FH controller, you will not be able to restore the edited program to the FH controller.
I would to recommend to use same versions software both FH controller and PC.
