What version of R and BioC packages are you using? Send the output of
sessionInfo() after you get the error. I suspect that you have an old
version of R. One thing to try is to upgrade R and reinstall BioC.

Nayeem,
If you can try this again and send the list an output from the
command:
sessionInfo()
it may help people determine what might be the problem.
