I had a simmilar issue with the HUB of the Invation games on CN.
When the last game came out (Billy metel Face from grim and evil) The hub did not advance, it showed that the game was not availible.
I loged into a second account on my compututer and went to Cn and the game worked correctly, so I went in and deleted the games Sockwave file under my internet cache and it then worked.
Maybe your glitch is a similar issue/resolution ?
