I can't necessarily help, but it is important that you tell what kind of a computer you have and also what you want to do after you connect the two devices--for instance, do you want to edit what you have recorded on the computer? Do you want to burn it on to a CD?

As a general rule, devices comes with a software CD which features the software you need to connect, as well as programs that you might be inclined to run, and, now days at least, PDF instruction manuals that tell you how to do everything--if you're lucky, there will be a hard copy instruction manual for the recorder and a booklet on using it with your computer with a pamphlet or card that tells you what to do to start the whole thing up--
