Avrdude cant find USBtiny.

I told my robotics team that this year I would learn WinAVR. But I have encountered a issue. I have iterated through the steps on how to properly install this programmer (
http://www.ladyada.net/make/usbtinyisp/ ) time and time again. I have also referenced the "HELP!!!" section on the website. Despite this avrdude refuses to recognize my USBtiny programmer device.
" avrdude: Error: Could not find USBtiny device (0x1781/0xc9f)
avrdude done. Thank you. "
Can someone help me out?
Thank you! :-D
P.s I know I can sometimes be unclear as to my purpose. If any further clarification is required please let me know.

My impression of USBTiny programmers is that they are junk. I've read multiple threads on Sparkfun's forum about problems people have been having with those. Looking at
http://forum.sparkfun.com/viewforum.php?f=7 you can probably see at least 5 threads about a problem with that programmer. I would recommend getting a more exepnsive programmer seeing many responses saying that the cost of a more expensive programmer pays off.
I don't actually have one of those but that's just what I've learned about them after reading reviews. I'd double check to see if you have all your drivers installed correctly. I believe it's supposed to emulate a parallel port and being interacted with via the usb port but I'm not sure.
Post your AVRDude command here just to make sure it's formatted correctly. Here's also a thread that a guy with the exact same problem as you started:

So I got ripped off?

The way I installed them ( Windows Vista ) was the exact same way this guy did:
