[BioC] Odd warning in simpleaffy, using quality control

Hello,

I'm trying to run some quality control (qc) on a bunch of raw files
retrieved from ArrayExpress, using simpleaffy, with the code:

mixture.batch <- ReadAffy()
mixture.qc <- qc(mixture.batch)



However, when I get to an experiment which has not used the
"hgu133plus2cdf" platform (In this case, it is experiment
E-GEOD-33443), I encounter a warning:

Error in getCdfInfo(object) :
  Could not obtain CDF environment, problems encountered:
Specified environment does not contain hugene10stv1.r3cdf
Library - package hugene10stv1.r3cdf not installed
Bioconductor - hugene10stv1.r3cdf not available
In addition: Warning message:
In qc.affy(unnormalised, ...) :
  CDF Environment name ' hgu133plus2cdf ' does not match cdfname '
hugene10stv1.r3cdf '


Any help would be appreciated, thank you.
