Hey I have a probelm. I have everything I needed downloaded all but the extracter but I don't need it. But when I try to edit anything .dds photoshop says it's a inncorrect file. I don't know what the probelm is. But I am thinking it's because I have cs5 when this guide is for cs3 and cs4. I don't know if it matters but I have a ATI Mobility Radeon HD 4250 graphics card and the plug is made by nvidia, could that be the probelm?
