Halo Waypoint codes entered, no new cRs in Reach

Could someone please tell me if the Halo Waypoint codes for the terminals in CEA still give you 100,000 credits? Or has that been discontinued? I went into Waypoint from the Halo Reach start menu, entered all 10 codes this morning, and all 10 were accepted. The Alpha Halo Archive in Waypoint now reads “11/11”. But when I logged back onto Reach, my cR count was the same (I wrote it down prior to entering the codes). Should I instead be going into Waypoint through CEA instead of Reach? Could that be my problem?

I also noticed that the videos don’t play after you enter the codes. Could this be causing the problem, or is this a known issue given that support for Waypoint has ended?
