I would say that's pretty explanatory. You've asked it to use the  
first column for row names, but apparently there are two rows with  
the same name, and we can't have that.
Perhaps you might want to try to load it without the row.names=1  
part, and then use:

duplicated(exprSet[,1])

to see which rows are the ones with the same name.
