NGCBUILD .. MDT error on Virtex 4

Hi,

I have been facing the following errors when I tried to generate a
bitstream for the Microblaze softcore to be ported on to Virtex 4 FPGA
board.

Running NGCBUILD ...

Done.

Earlier when I was using the older version, I never got these errors
and everything was working perfectly. But when the licenses got
expired, and when I installed the 7.1i versions of EDK and ISE these
errors started occuring. Can anyone please throw some light on this
issue. I have been stuck with this for the past 4 weeks and am not able
to find any resources on the internet for this. It would be great if
anyone can let me know about this.

Thanks a lot.
