I had the same problem as Joerg with the 4.02 update.
The fix is simple:
After the installation of the bugfix, but before the next start of Vue, delete the directory called 'german' or 'language' or whatever (I don't have Vue at hand) in the Vue program folder.
This fixes at least problem 1), maybe also the others.

By the way, can this Version 4.03 import the neftis hair from a pz3?
