I've got the same configuration as yours (you told me you haven't nothing connected to the IDE Primary Channel, 40 pin-the second from left to right, red line down-), as you know, and it works for me. The only problem I found with the Idefix (which I've got installed in 4 different places in the HD I bought) is that it only worked with the "Install software" icon, (which only appears in mine in one of the Installed Idefix programs), instead of the Find device or others.
Do you have you got the original program, registered, and have you tried the Install Software Icon?
(Perhaps it's a simple question, but that's what made mine work)
