Where is the text?

So after a couple days I decided to "plant" my Magic game on my actual Windows 7 computer in the C drive, so I did, and the text vanishes on the cards! When I'm running it via my USB Drive (or even if my USB drive is IN the computer and I run it via the C drive) the text will be there and I can play it. But when I remove it, all the text on the cards and the text and some pictures in general will vanish. Is there a cure for this?
