Arduino-Flash(NETlab)

I tried connect flash and arduino and I want to make images change by sensors.
I followed a tutorial in
http://www.netlabtoolkit.org/learning/tutorials/getting-started/

When I put 'Analogin' on the screen and clicked 'test movie', poped up error which said

--->parameters file error: Untitled-2.xml, ... setting defaults
Widget 'instance1' connecting...

Does anyone know what problem is ? I really want to finish my project during the week.
Please help me.
Thank you!
