"Course Plotted" - Annoying.

[Feuer Frei!]

Kaleuns
after every new course plot on nav map, the player gets the very annoying "Course Plotted" cry.
Is there a fix\mod that alleviates my ears from this rather annoying part of the game?

Also, i understand that once you have installed the game in a particular language (my case is installed in english) am i correct in assuming that you can't change the language to german for example?
I have some german language mods and fixes but obviously can't use them since the install language is English.

Thanks in advance
