Hey sub, dumb question I know, but have you updated the drivers for it yet. That would of been my first recourse, but im a driver manic so i cant help it to much.
Also, and maybe this may not work, and I might catch some desrcetion over this, but have you tried tech support with sony. To my knowledge you dont need account to read forums. Go here

Towards the bottom of the page is a Technical Support board. Search there, or even better, post your problems, but say that your not able to connect to their servers, and not the Emu's. They will more than likely have seen that issue and can direct you to the way to fix it quicker than any of us can.
