HD Clone 3.9.5 doesn't work

Hello
I used HD Clone 3.8 with pleasure and bought the 3.9.5 release today because I need to downsize some partition to test an SSD on my computer.
The download of the ZIP and EXE files where good, it unzip and I can start hdclone.exe, but when I choose "start HD Clone", nothing happen : the blue window open and nothing in it.
It does the same thing on my notebook (Windows 7 64 bits) and my desktop PC (Windows XP 32 bits).
HD Clone 3.8.5 works with no problem on those two computers.
Where is the problem ?
