Greetings, I installed the DirectX 9.0 SDK and almost everything works great. On my system, the Texture Tool throws an error that it couldn't create the device, this doesn't make sense!! Here are the specs on my system: P4 2.8Ghz 1MB cache 800Mhz FSB Samsung 256MB DDR400 RAM (I am upgrading this :-P) 256MB nvidia GeForce 6800 PCI express So, my computer is powerful enough, why isn't it working?!

Presumably because it can't create the device.

Isn't the source code for the texture tool included with the SDK? If so you could try building it with debug information turned on, and run it (with DirectX debugging turned on too, Forum FAQ) to see what DirectX tells you the error is.

Even without building it you can use an external tool like DebugView to capture the debug output (providing you installed the debug version of DX).
