I was too lazy to disable this Samsung account after that.
8 days later...
I suddenly have my games panel!! Wow! Then I become nervous... did it update its firmware?! I immediately checked, turns out I'm still on 2130

Then I went into this games panel, installed some games, everything fine, now let's play.
But when I try to launch any of the games I installed, it says "Loading..." and then "Function not available".
So I've got my games panel, got my games installed. But I can't play them now. Does anyone know what could be going on?
