You cannot update a package if it is loaded, because Windows locks the dll.
Hence start R without loading nlme (that it is loaded might be because 
you mentioned it in some Startup file such as .Rprofile or a saved 
Workspace image loads the package for some reason - don't know whether 
this could happen for nlme).
Hence RGui --vanilla might be right for you. Then update.packages().
