PowerPro Error: Cannot access script file "SelectNfiles"

[Heronjr]

I am trying to use the script SelectNfiles.txt by Vochomurka (http://ppro.totalcmd.net/Scripts/SelectNfiles.htm). I followed the instructions to use a button in TC, configured it and running the instruction runfile.SelectNfiles("10") I always receive the message:

PowerPro Error
Cannot access script file SelectNfiles

The script SelectNfiles.txt is in the PowerPro\scripts folder and the plugins win, tc, childwin are already at the plugins folder. The PowerPro bar is up in my screen, so I think PowerPro is running (or not?).

What am I missing here?

Thanks in advance,
Heron
