You haven't said which version of limma you were using with R 2.0.1. If it 
was limma 1.8.18, then the change must  be with R. If it was an earlier 
version of limma, I can check for limma changes.

When people have had this or similar errors in the past, it has usually 
been because a problem with their input files. It would be helpful for you 
to give the header lines from the first of your input files.
