yes naz, that's what I was referring to, and I can bet this is actually doc_uk's problem. adding "D:\Program Files (x86)\Steam\steamapps\common\il-2 sturmovik cliffs of dover\Launcher.exe" -mod=MODS\BpSoundSuite" is just a part of kegetys' setting, another is to modify the Launcher.exe.config by adding the kegetys .dll into it, as naz had the kindness to copy/pasted it to you (please
READ kegetys tool readme).
Have a look in
HERE, please..
