I am trying to use Express Scribe to translate some audio CD's that I have. I too am having difficulty understanding the Help of Express Scribe on this: when I load the audio file I get an error message that states: "Loading of the speaker failed. Please check that a valid speaker is selected". I have not been able to see how to do this. Are they referring to ES or to DNS. Apparently some users have progressed beyond this point so I would appreciate any help that you can offer. Regards, winsurfer
