well, the above says it "all":
- You have an .RData  file that is trying to be loaded
  (in my view a proficient ESS user should never work with session .RData ..
   the source is real;  expensive objects should be save()d and
load()ed / attach()ed explicitly)
- that .RData contains objects of a class which is defined in package
'iterators'.
  --> when R is trying to load() .RData it also tries to  require("iterators")
    and that fails; as I assume you have not yet re-installed the
'iterators' package for that version of R.

-- all this should not be related to ESS at all, and you'd see the
same message when starting R
 "from a terminal".

- You solve it by renaming  .RData to something like   myprev.rda
   start R
   install "iterators" (and all the other packages you need often)
   load("myprev.rda")
