R help - Nov 2010 - Updating R packages

I have been trying to update some R packages but I get the following error.
Can you advise how mow to get around this . I am using the R for 64 bit
windows.

--- Please select a CRAN mirror for use in this session ---
Warning in install.packages(update[instlib == l, "Package"], l,
contriburl contriburl,  :

If you want to install packages into this library mentioend above, you 
need the corrwect permissions to do so. For example, start R with Admin 
privileges or change the permissions of the library.
Or maybe even better: Use another library than the base one to install 
contributed packages into.

Note that you are under R-2.11.1 and if it is the 64-bit version of it: 
CRAN does not support 64-bit R-2.11.x any more: please upgrade to 
R-2.12.0 which comes with bi-arch binaries for both 32- and 64-bit 
operation.

Best,
