[BioC] troubles with GEOquery

[Pascal Barbry]

Hi all,
I have troubles trying to download GSE files from GEO:
library(GEOquery)
GSE6281 <- getGEO("GSE6281", GSEMatrix = FALSE).

Surprisingly, the example found in the help file is working nicely:
gse <- getGEO("GSE462", GSEMatrix = FALSE)

?????!!!.............

My troubles started after switching to the new version of Bioconductor. As I am using a Windows OS and that some of the 
getGEO options are not windows-proof, I was wondering if any others had experienced a similar situation? Any idea 
(outside swtching to Linux) would be appreciated.

Thanks in advance,

Pascal
