Yep! Tried three different downloads. and each one sized up just fine. Now My computer? That's an idea. I can try some other computer though I really don't know anyone with one! Odd, I know.
Still: there hasn't ever been a problem. I have upgraded the n800 before, same computer, same cable, same port, worked just fine. It finds it now just fine. blah-blah. Will seek out another computer.
