Hi dolyl, you'll need this: http://developer.nvidia.com/docs/IO/1176/ATT/msvcr70.dll (copy to windows/system or winnt/system), and this: http://developer.nvidia.com/docs/IO/1176/ATT/dds.8bi (Photoshop Plug-in) for Photoshop support. If you just need to convert them directly into .tga, download this: http://developer.nvidia.com/docs/IO/1176/ATT/DXT_TOOLS_v5.19.zip and use the readdxt.exe. In that final download, you'll also have the Photoshop-Plugin and the .dll needed for it. hope this helps, -Sascha.rb
