360 data transferring question. Help greatly appreciated! Urgent-ish question.

So my girlfriend and I have been playing Skyrim religously and she recently bought a 360 for herself. Now we tried copying the data from my Xbox to a thumb drive and opening it up on here but it says the data cannot be transferred between profiles. I tried copying and moving it but neither worked. And I can't access the load options from the thumb drive on the skyrim load screen.

So the question is, how do I transfer data from one Xbox to another when it says I can't copy from profile to profile. I have the saved data on a thumb drive right now. Any and all help is appreciated guys!
