Problem with weltmeister SF2 ( no sound on certain notes)

[accmus]

Hi
I have loaded the new Weltmeister SF2 into my new audigy SE and they sound good, and are a marked improvement on the original soundcard accordion sound.

I do however have one problem:
Depending which file I use, deoending on the composition, I do not get any sound on "F" below middle C, and like wise no sound on "F" on the top line of the stave and above.
Can anyone help me on this please.
Thanks
