I have all ND games to date, and have them all installed. When I installed, I went in chronological order. Lately, when I pull up ND Centeral, Secrets Can Kill (original) is greyed out, and instead of a play button, the button says buy. Also a few other games will not load from ND Central, no matter how many times I click (The ones that won't play from there, aside from SCK are: Last Train To Blue Moon Canyon, Danger By Design, The Creature Of Kapu Cave and The While Wolf Of Icicle Creek)
Has anyone else seen this or have any idea what I could do to fix this?
