If you can't get the CWM version to work, you can try the TWRP, but they're basically the same image with just one file changed. TWRP uses the touch screen, CWM uses the buttons.

Does it take a couple minutes to flash?
Make sure you close out all your Windows Explorer windows (windows that show files on your pc) or you'll get an error.
