There is a hidden getsusp.opt file in the same path where getsusp.exe was executed from - could you delete it and try again? This file retains the settings from previous builds - best to launch newer versions from a new directory path.
Let us know if this helps
Thank you for the help, but I have found the reason now, it was not the old getsusp.opt file -> it was the path c:\Script\GETSUSP\
If I rename it or use a subfolder - it works
