Dear Luis,

The annotation file "HuGene-1_1-st-v1.na30.hg19.probeset.csv" contains 
probesets which are not present in the pgf-file. For this reason 
Affymetrix has updated the file to 
"HuGene-1_1-st-v1.na30.1.hg19.probeset.csv". Could you please use this 
annotation file.
(Files "HuGene-1_1-st-v1.na30.hg19.transcript.csv" and 
"HuGene-1_0-st-v1.na30.hg19.transcript.csv" should be identical.)

If you still have problems could you please use Rterm with verbose=TRUE 
and send me the complete output.

Best regards
Christian
