[BioC] GEOquery/virtualArray package error

Hi,
 
I am trying to use the virtualArray package, using the example code in the Vignette document, pasted below:

> library(GEOquery)
> library("hgu133plus2.db")
> library("hgug4112a.db")
> library(virtualArray)
>
> GSE23402 <-getGEO("GSE23402",GSEMatrix=T,AnnotGPL=FALSE)
> GSE26428 <-getGEO("GSE26428",GSEMatrix=T,AnnotGPL=FALSE)
> GSE23402 <- GSE23402[[1]][,1:24]
> GSE26428 <- GSE26428[[1]]
> exprs(GSE23402) <- log2(exprs(GSE23402))
> exprs(GSE26428) <- (exprs(GSE26428)/20*16)
> 
> annotation(GSE23402) <- "hgu133plus2"
> annotation(GSE26428) <- "hgug4112a"
> 
> my_virtualArrays <- NULL
> my_virtualArrays$iPSC_hESC_noBatchEffect <-virtualArrayExpressionSets()


This code worked until about a week ago, but recently it gives me warnings and errors. In particular, I get the following warning:
 
> Warning message:
> In download.file(myurl, destfile, mode = mode, quiet = >TRUE, method = >getOption("download.file.method.GEOquery")): downloaded >length 64514067 != reported length 200

And also this error:

> Now preprocessing raw data of GSE2527: Annotating expression values with SYMBOL...
> Error: 2 errors; first error:
> Error in array(x, c(length(x), 1L), if (!is.null(names(x))) list(names(x), : 'data' must be of a > vector type, was 'NULL'
 
 
I am wondering if this issue is related to an error to the GEOquery package or the virtualArray package. Is there something wrong with my installation of R or any of my packages?

Regard,
Nafiseh
