I'm not an expert in this but maybe this helps somehow.

That error means that you don't have annotation (CDF) package for your 
affymetrix chip.
You can search here 
http://www.bioconductor.org/packages/release/data/annotation/
for the appropriate CDF package.

Also, you can chack makecdfenv package.

Best Wishes,
Maciej Jończyk
