Although upgrading is never a bad idea, this should not matter in this 
case: R-2.12.x for Windows will look into the 2.12 binary repository for 
Windows with the right version of nlme.

I suspect a broken installation of nlme in R's main library and that the 
re-installations go into another library or so.

But since we do not have any output of the install processes nor the 
currently available libraries on the search path etc. it is hard to know 
what is going on.
