If you manage to get that to work properly, please let me now.
I have played with that for almost a day now without getting it to produce a properly rendered translated page. Translated pages are accessible but the CMS never seems to apply the theme correctly, independent of which theme is selected.
(see http://www.silverstripe.org/all-other-modules/show/20463 )
what exactly does not work?
so did you get the latest files?
just download the zips there.
