Hi,
When you say "server", do you mean Windows Server 2003 ?
What's happening here is, when you select .wav and click the Encoder Settings button, Switch actually calls up a configuration window that is supposed to come standard with all versions of Windows. It appears that your Windows Server 2003 system (or whatever it is) does not come with that dialog installed.
And if this particular dialog is missing, that would probably explain why the conversion failed, because our software relies on the presence of the dialog to be able to convert from/to .wav files.
There is really nothing I can do for you other than to find out if Windows Server comes with patches or something that installs the wav configuration window, which I will do of course.
Re: au, aiff, gsm - yes they are currently greyed out, we will be adding settings boxes for them at a later date.
Thanks for your detailed post, always helps.
