Are you installing it in the default directory? I would check to make sure that the NAudio.DLL file is present. Just did a clean install on an xp machine and it does load the files it needs so the build is ok.
Just did a restart and then did the reinstall again. This time it worked. Go figure.
When I load the VC, it puts the scanner in "Hold" on one of my systems trunk frequencies by default. I seem to recall that before .9M, when VC was started, it would simply continue doing whatever the scanner had been doing. Now, if I actively scanning and open Virtual Control, it places a trunking frequency on "Hold" until I give it a command to resume scanning. Is this normal?
