DE5-NET JTAG Configuration Problem

Hi all,

I tried to program the Stratix V FPGA on the DE5-NET board through the UBS Blaster cable. Each time, the programmer goes up to somewhere between 95% - 98% and fail. The error i get is "Error 209014 CONF_DONE pin failed to go high in device 1".
I also noted that in the LED array near the USB blaster port on the board, only the JTAG Tx LED blinks while the programming is going on.

Any ideas why this is happening and a way work around this is much appreciated?
