An important thing to remember when working with the executeable item type is that only the 'Command-Line' parameter is available for that item.
The following page identifies each item-type with its compatible parameters: http://www.empirisoft.com/medialab/h...parameters.htm

The easiest way to get the output you want is to either locate the .EXE in the same file that the .que is in, or use a hard-coded path that goes all the way back to your root drive.
If the file is in the same folder as your .que file, you can do something such as: files\cyberball.exe
Whereas if you use a hardcoded path, it may look like: C:\MediaLab\New Experiment1\files\cyberball.exe
