I am sure that you must get the updates till it registers and when it does the subscription must start from that date.....:)
More over its better you let it run like this for a few days and then check it.... meanwhile I will check out and see if there are any server related issues...(it will take 2-3 days for me to ensure that there are issues).....
I mean you can't phone up some one and ask "is the server off?"
jokes apart...
There might be many reasons for the server link to be poor ( again there are very few/no other issues like yours so something big as a server is not switched off it must be some thing down the line or on the box) i will investigate if possible...
meanwhile you are protected and the updates will be going through too.....
again... do try Luke's suggestion and then see if it helps....

happy
