Andi:
I have worked with Finale and Vienna SE the last couple of months and I created my own HP prefs for Vienna SE some time ago.
I took a brief look at the HP prefs on the VSL site and they seem ok, just one thing: Double Bass, Bass trombone and tuba has different keyswitches than the high pitched instruments (as I'm sure you know). You'll need to add these instruments and assign the correct keyswittches to them (C6-D#6 (F#6)) to the HP prefs to get them to work properly.
I could send you my HP prefs if you are interested.
