Typically when I have encountered others who have had this error occur
it is because they have corrupted data. For instance this piece of
demonstration code will generate the same error:
library(affy);library(affydata)
data(Dilution)
Dilution.Corrupted <- Dilution
pm(Dilution.Corrupted)[1,1] <- 30000000
# that is an extreme value outside the
# range of normal raw probe intensities
eset <- rma(Dilution.Corrupted)
My suggestion would be to examine things along those lines.
