Some of the videos date back to early 2011, and although still relevant to the current version, may not have had the more recent updates applied, at the tiime it was made. It is a constant effort on our part in the UK to rectify translation and localisation errors, and still do find the odd dialog hidden away with a German word in.
Most of the earlier problems related not to German words appearing in the source code but in Window / Door / Wall components as a result of the material lists not being translated. (Details from this components then appear in the Window dialog). Its not just translation that we have to update, but also localisation, e.g default wall sizes, cavity wall sizes etc.
All of these are rectified in the localisation updates that we issue, which normally update the material list and layouts etc.
If you are using v4 then please allow it to automatically update, and these localisation issues will be resolved.
