I think Martin already responded to your question as you posted it on
the bioconductor list.  So for the archive, please look there:

The issue of dealing with serialized instances of classes when the
definitions of those classes get updated is a difficult one.  We have
some improvement in the devel version of Biobase that should go a long
ways to easing these issues.  For the interim, we will try to post a
helper function that you can use to update your saved data sets.
