Problem with Camera RAW file?

[apearlb]

We just got a new 5D camera and have enjoyed using it but lately I've noticed something strange happening to some of the RAW files in the Adobe Bridge. When I first upload the photo seems fine but then when I close the Bridge, come back at a later time there are sometimes 1 or 2 files with color streaking. The best I can describe it is that it reminds me of what would happen if you opened the back and exposed the film on a film camera. (I swear that when I uploaded the picture it was fine). I've never seen it on a JPEG file so I'm thinking this is a RAW problem. Is something wrong with my sensor on the camera for RAW files or is Adobe Bridge or something else causing it to lose data? I uploaded a sample of one of the photos it did it to. I'm a little nervous because we have a wedding we are shooting on Friday and I don't want to have 1/2 the images be screwed up!

Thanks!
