10.1 Problem: "Cannot access secured data" and "invaid raster dataset"

[JerryGarcia1]

I recently upgraded to 10.1. When I try to add certain rasters to ArcMap I get a window saying "invaid raster dataset" and then a second window that says "Cannot access secured data"

I was able to use this data fine before the upgrade. Does anyone have a workaround?

Did you ever figure this out? I'm getting the same error message.
