Problem with 6i25 + 7i77 PWM Pins

Hi All,
I plan to upgrade my MH400 e with Linuxcnc. I bought a 6i25 + 7i77 and now I´m starting to configure the Cards In/ -outputs for my Mill. I have a fresh install of Linuxcnc (2.9.4) and run into the problem that whenever I try to configure the PWM Signals of the 7i77 the tap just isn´t there. I had a bit of success when i tried the PnCConf Wizard on the Live distribution, but there I couldn´t configure the encoders on the 7i77. I tried older Versions of Linuxcnc but that also didn´t help. I hope someone can point out my mistake, that I am obviously making because it seems to be working for so many others . 

Thanks for your help,
Simon

Possibly a language/locale issue (this has been noticed before on pncconf)

2.9.4 pncconf gives me this after selecting 5i25+7I77x2 with one 7I77
and accept component changes:

 

Sorry for the late response, you were right about it. I did an fresh install in english and now I can configure my card.
