Dear Sir or Madam,

I would like to analyse Affymetrix Mouse Diversity Array, extract BAF LRR 
using CRMA v2
I followed CRMA v2 vignette, and I get always an error during process()  :

Exécution arrêtée

All packages are updated with the latest releases.

here is sessionInfo()

here is the script

Easy to reprodruce.
Thanks in advance for your time and ideas...
