System acts like I do NOT have active subscription to on Demand programming

Hey, a few days ago, I had DirecTV installed and the on Demand connections made to my router.  After the obligatory 24 hr wait period, I have still been unable to access on Demand programming from my HD DVR.  All the menus and options show up, I'm connected to the internet per network testing, and on Demand has been activated by DirecTV.  When I go to add a program to the queue, however, I get a small pop-up at the lower right hand corner, asking "Would you like to subscribe to this channel?  Call 1-800-DIRECTV or go to directv.com."  So, it acts like i've never subscribed.  I have talked to multiple tech support reps, and nothing is working.  Has anyone experienced something like this? What to do?  Thanks! --Lynn
