Cant find SATA drives only USB drives

Major issue: this software cant find installed SATA drives on my desktop computer, only the external USB drives.

My main reason for purchasing this program was I have a few Gbs of files I accidentally deleted on my laptop. I also have a desktop MacPro and I connected the two over wifi to access my MacPro from my laptop. That way I can test out different file recovery programs on my MacBook without having to install and possibly overwrite anything to the laptop, except this program will NOT run that way on my laptop at all. All the other programs I tested out would scan and search the laptop drives but this one did not allow to start.

The interface is unique but a little too baroque for my taste, it has some very cool graphics but it doesnt really make it any easier, more logical or better to use the software. A bit over the top. That said the software does NOT run properly. Im running OSX 10.6.8
