Great thanks TorpX,
that did it.
One more question:
I'd like to play the german campaign now and would prefer to have german speech for more immersion. How can I get that?
I am unable to use the silent_hunter_4_german_voices patch because of my silent hunter 4 gold version. There should be a special patch for that version, but it seems to be unavailable now.
Originally I thought about playing it with the Operation Monsun Megamod, but since this seems to be incompatible with RFB, and I really love the things RFB did to the game, this is not an option.
Is there any other way?
Thanks again,
Skyworm
