New Arrive Owner, Can't update Program Error Code 801811A5

[JohnMcD348]

OK, I got my Arrive today. First thing I see after it's activated and running is the notice that there are program updates available. I installed Zune on my Win7Premium system and plug it in. The Zune program installed an update for itself and then goes to the phone. It tells me there are updates for the phone and I choose to install them. It tries to install and then comes back with the Error Code 801811A5. Supposedly the updates are for some errant certificates or something.

I've restarted the computer, gone through my Norton 360 and made certain the Firewall was set to allow instead of automatic. It was Automatic prior and didn't work either. I checked the Windows knowledge base and that didn't solve anything either.

Any ideas?

Thanks
