[BioC] annotation problem with hgu133plus2

[Yanqin Yang]

Hello Seth,
 
Thanks for your suggestion! I did update all packages by choosing 'update packages' option in the package menu. I tried to rerun my code and unfortunately something wrong with ReadAffy function. The following is error message. Would you help me out? 
 
Really appreciate your help!
