It's a 2 gig cpu, 2 gigs RAM, Win XP, C drive is 75 gig, F drive is 150 gig. Yes the program does run from the USB HD. The computer sees the USB too. I did click on the setup file from the USB HD to install to the internal F drive of the computer. I think I answered all the questions.

I did call tech support last night and the suggestions they gave me didn't help. They said if the suggestions didn't help then I might have to send the USB HD back to them, which I don't want to do as I'll be without it, but I may have to.
