No 22 Khz switching with Hauppauge Nova SE2 / S+

I use a Hauppauge Nova-se2 Tv-card in my pc and I seem to get only channels below a frequency of 12050 Mhz in H and V polarisation. I use Astra 19.2° East and a digital single LNB from Technisat.
I tried find some answer with google and it seems my tv-card doesn't switch to highband?
Is this correct? I read somewhere that Hauppauge cards might have a problem with the 22khz signal to switch to the Highband but I found no proper solution so far.
Did somebody had a similar problem? What can I do to check this?
