Have you tried using the cable you bought with Samsung's EasyStudio
software which you can download from Samsung's web site? The software
is not great but it does work, so if you still have problems it is
probably the cable at fault. I bought a cheap cable with some bizarre
software (couldbe the same one you got) and never got it to work. I
sent it back and got a proper Samsung one for a few pounds more and it
works like a dream.
Hope this helps
