Regarding that particular error (which you can encounter in other contexts too, so I think that is relevant nevertheless) it sounds like it would be exactly what it says there: "Not a DXT5 format DDS" -- when you make textures in Gimp (or whatever other program), you need to export them as DDS (DXT1 when they have no transparent parts, DXT5 when they do), otherwise the game won't be able to use them.
I don't think it would let you import a non-DDS with "Import from DDS" (for me that will filter for DDS only); maybe your image was a dds but with the wrong format?
Also, moving to CAS Parts since you are asking about CAS content.
