So, as most who mod no doubt know, Photoshop does not natively open .dds files, but NVIDIA has plug-ins that allow it to do so. I've installed them twice--.dds files even show up with a little Photoshop icon--but when I try to open a .dds in Photoshop, it tells me the file is not a valid Photoshop file. Anyone know what might be wrong? I'm using Photoshop CS2 and have successfully used the tools on a previous computer. I have a 64-bit computer, but should I be using the 32-bit instead since CS2 doesn't support 64-bit?
