That error most likely is shown when you use "Download EPG Automatically (recommended)" mode and there is no data available for your area. Did you enter a correct postal code? It is easy to forget to enter a postal code.
If you get the error when using "mc3xml" mode, maybe you need to download mc2xml.exe first. Google on "mc2xml" for more info. Again, make sure you have correct postal code.
If you choose "XMLTV" option, you need to provide epg data file (xml file) or an third-party executable.
