[BioC] ReadAffy Error: new versions causing problems?

These errors are typically caused by a mismatch between your version of
affy and your version of affyio. Given that you note that it works fine
using affy 1.12.0, this likely means you are uing an older affyio (not
the one from the current BioC 2.0 release)
