looks like you dont have this file "chars.txt" , you need it to open it , if you dont have it you get an error . Its impotant to extract the files before running the script.

Hope this helps ...

ty that fixed the problem, if the file was part of the package i din't get it. this looks interesting... what does the txt file do any way? it didn't write any thing to it...

This file is a very important part of the package , with this file the Key will be generated.

Thanks and enjoy
