Here's my guess of what's going on.  Does your exprSet, eset, have
data in both the exprs and se.exprs slot?  I suspect that the answer
is yes and that the rownames of these two matrices do not match (this
is what the error is telling us).

So I would compare rownames(se.exprs(eset)) with rownames(exprs(eset))
and make them match.  Then try the convert again.
