This usually indicates some problem with the installation. How exactly 
did you install these packages?

Anyway, the most efficient way to fix this is to re-install.

source("http://www.bioconductor.org/biocLite.R")
biocLite(paste("hgu133plus2", c("", "cdf", "probe"), sep=""))

Also, when you post please remember to give the ouput of sessionInfo() 
so we know what versions of things you are using.

HTH,

Jim
