I met today a computer crash and our maintenance officer had to reinstall
some components of the OS (MS Windows XP Pro) as well as the Internet
browser (among other things). Now, I cannot install packages from a distant
repository:

> utils:::menuInstallPkgs()
Error in .readRDS(pfile) : unknown input format
> traceback()
5: .readRDS(pfile)
4: .packages(all.available = TRUE)
3: .install.winbinary(pkgs = pkgs, lib = lib, contriburl = contriburl,
       method = method, available = available, destdir = destdir,
       installWithVers = installWithVers, dependencies = dependencies,
       ...)
2: install.packages(NULL, .libPaths()[1], dependencies = NA, type = type)
1: utils:::menuInstallPkgs()
> sessionInfo()
R version 2.8.1 Patched (2009-02-17 r47956)

other attached packages:

*********************************************

My browser and e-mail client are working, and I can display the list of
packages when I run utils:::menuInstallPkgs().

Did anybody meet the same problem, and how can I solve it ?
