You should have these files in the textures folder: "OctopusM.tif,OctopusBump.tif & OctopusBump2.tif". when you try and load OctopusBump.tif as a bump map in render properties a .bum file with the same name will be created. Open the cr2 in a text editor like "EditPad", every time you see "Octopus.bump" (near bottom) replace it with "OctopusBump.bum". each time you see "OctopusM.pct" replace it with "OctopusM.tif". It looks like the files were left compatable with Mac. -Rob
