You should recreate your DMS one more time and leave it bone stock. Don't edit any ini files, don't use phatvoice, don't copy your plugins over. Don't make any mods at all. Don't even add any playlists, just use the default one that PMM creates. I'd say DO let the firmware update one more time. Then see if it works. If it does come inside and make one small change. Maybe change a playlist or add a playlist. Try it. If it works make another small change. Maybe try copying your plugins this time. Try it. If that works try SOME ini mods. Try it....etc, etc. When it stops working, you've found the problem. If it doesn't work bone stock, then I would guess you have a bad box, maybe a bad cable, or possibly a virus messing with things.
