When the Quartus Programmer failed, there will be messages displayed in the Quartus II console. So minimized Programmer so you can see what's displayed in the main Quartus II console. That may give you a clue. Also I've seen the same problem before and when I close Quartus II and/or reboot my PC and try again, it'll work. Have you tried that? Also, your JTAG voltage of 2.5V for Cyclone III is correct so do not change that to 3.3V. That'll kill the device.
