Unresolved Perfect Dark XBLA Game Save Corrpted.

So, I've recently found your tool to help me get a save onto my USB Device, how to do everything and all that. I read all the instructions, I get it successfully injected and all, plug it into my 360, and try to load the safe, only to be told it's a corrupted save. I tried a save from this site, and one from another one, and each time it says it's corrupted.

I'm just trying to look for a save that unlocks everything in perfect dark, a 100% save. Can anyone tell me why it might be corrupted, or what is actually happening, or what step I might be skipping, even though I read over everything 10 times?

 

Guess I wont be getting support of any sort, in the support forum....
