Miktex 2.9 issue for genbib.bat

Dear colleages,

recently I have changed the Miktex software version from 2.8 to 2.9. At this
instance, the following error message have appeared when I tried to build my
urithesis-based document:

"Error: I cannot write on file genbib.bat".

This error did not appear at 2.8 version. In fact, I have returned to
version 2.8, without any similar error afterwards. I though that perhaps the
OS would be the problem, but the problem stills for either Win7 or WinXP. I
have used WinEdt and TexnicCenter as Tex--editors, with the same result.

Thanks in advance for your commentaries, collaboration or some solution
about this problem.

Best Regards,
