Unknown Profile HELP!

When I try to put an xbox 360 world save that I downloaded from the internet into horizon with my profile in it it says that it has an “Unknown Profile” can someone plz help

Move your profile onto your USB device, and then move the save onto the USB. Once that is done, save the world file to your profile. If you have any further questions let me know.

That’s normal. You can just plug the HDD on to a PC with a SATA cable/transfer kit and your profile can be seen.
You don’t really need to move your profile.
