I figured out what my problem was.
The utility generates the report file as soon as you enter your number of fighters and press "enter" BUT nothing actually shows up in that file unless you enter "0" to exit the program.
Once I "exit" the program by using the "0" it worked, but if I exited the program by clicking on the "X" in the top right corner of the box nothing would be placed in the file.
I probably made that sound more confusing than it was
