I would suggest you install the Capture demo on the machine you are trying to run the presentation file in order to have access to the Capture network settings. Once you have run the demo try and feed it with dmx from whatever console emulator you are using. Once you succeed int that run the presentation file again and usually it will pick up the network settings of the Capture installation.
It is in our future plans to reveal network settings in the presentation files, but until then the above serves as a workaround.
By the way which console emulator are you using?
