Problem programming CoolRunner II xc2c256_tq144 CPLD using IMPACT

I was trying to program xc2c256_tq144 (CoolRunner II) CPLD using ISE Project Navigator SW version 7.1.04i. I used parallel III cable provided by Digilent to program the CPLD. But I am getting error "iMPACT 583 - '1': The idcode read from the device does not match the idcode in the BSDL file". I tried to view BSDL file but I don't have a clue as to how to modify device IDCODE so device id and expect device id matches. Does anybody know what's wrong here or know how resolve this issue? Thanks in advance.

Best regards, Nabin

Nabin, leave the bsdl file alone, try first to reduce the speed of the cable, and if still doesn't work post the output of impact here to see how different they are (I mean in which way)

its an generic warning that usually doesnt tell you at all whats wrong there is no need to touch the BSDL file, there is some JTAG problem with your setup so you need to troubleshoot it

try reading the chain with chipscope does it show correct ID?
