Can't open nor save file to disk with Quicktone software

Hello everyone,
In order to configure an usb guitar pedalboard, I am using a software called Quicktone. It works great in interacting with the pedalboard.
My problem is when I am trying to upload a patch or try to save a configuration to my hardrive.
I can go to the disk, find the patch and click upload, but nothing happens. When I save a configuration, it says saved but the file is not written on disk.
Does anyone encountered such problems or have any idea of what happens ?
Thank you
