Oh, sorry. The above is a spelling mistake. I have been using foward slashes. I have tried to type both sound/ambience/uspointcaptured.wav f.ex. and just ambience/uspointcaptured.wav. And i have tried to move it to all posible folders concerning sounds in half life, but it still makes the same problem.
It says; Error: Failure to transmit file: sound/C four times, which i do not understand... so does anyone else has a suggestion.
