I am a newby and I am wanting to do a 3 axis skull. I don't have any equipment yet. I have downloaded Brookshire's demo software and I cannot get it to load an audio file . So far I have not received any help from their support, except to say that the demo should load an audio file. I am using windows XP . The error I get is when I select audio file it says the file does not exist , I get a popup that asks if I want to change file name, (yes or no). If I answer no it loads the waveform but does not play sound. I have used these audio files in Light O Rama light shows or anything thing else that I want to. Sorry for the rambling . Thanks for any help.
