NEW DVR BOX

I just swapped out my main DVR box.  I can not seem to watch many of my normal channels.  I get two different error codes when I try to change the channel...XRE-03121 which states that I made updates to my account and the changes may still be in progress.  and XRE-03062  which states comcast is having trouble on their end. This channel is currently unavailable.   

I did not do any real change to my account, only a new drv box. Usually it is plug in, set up and play.  All I get is errrors.

Is this due to no back office techs to program my change to a new box? I have spokent to the foreign call center to no avail and they did not resolve my issue.  What next?
