Error deleting raster in file geodatabase

I'm trying to delete a raster within a file geodatabase in ArcCatalog (ArcView 10.0). When I attempt to delete it I get the Delete Failed error below: (raster name is "e2797_02_3")

Failed to delete selected object(s)
The application is not license to perfore this operation
The table was not found. [e2797_02_3]
The table was not found. [fras_ras_e2797_02_3]
The table was not found. [e2797_02_3]
The table was not found. [fras_ras_e2797_02_3]

Also when I right-click on the raster and select "Properties" I get the error "Failed to Open Dataset." Is there any way to get around this?

Thanks!
