I was not able to import my created soundbank files. The editor refused to write to "SoMmusic.lsb" which was created by me through the ressources manager, so I would have a package for my new music. It was protected just like the campaign. Removing the protection resulted in, yet again, corrupting main.
And while importing the editor also asked for some file selection. But there is no text. It just wants some file which is not there. No way to find out what kind of file or where to get it from.
No clue.
You must however copy (and in Wwise set the correct file path) your soundbank and .wem files to the game folder or else you cannot even start importing.
