I know you expressed interest in running NAS4Free, it might work better for you, or you could load FreeNAS 8.0.4-MM and it works great, then wait until 8.3.x is stable. I'm still unsure why 8.3.0-BETA2 isn't working for you, not with the specific problem we saw. BTW TeamViewer is nice. Go figure that my father (75 years old) has been using it with an equally old friend for over a year so they can help each other out.
If you ever identify the problem, please post it. And good luck, I know you will need it.
