Hi Sebastian,
Please always give us the output of sessionInfo() as well. Just telling
us you have BioC 2.0 isn't sufficient. For instance, I get this to work:
> dat <- ReadAffy(filenames=list.celfiles()[1:5])
> eset <- gcrma(dat)
Adjusting for optical effect.....Done.
Computing affinities.Done.
Adjusting for non-specific binding.....Done.
