I don't know , possible. Seems like no one except me experienced anything at KZ2btw.keyn/Jardel, I have not encountered any KZ2 slowdown. Could be related to the increased load due to newer Slim owners and returned KZ2 players ?
Here is another but more interesting thing I've experienced [ not sure if it is related to fw3.0 though ] ;
I've downloaded Echochrome Demo long time ago. After upgrading to fw3.0 , I tried to launch the game demo but it said I need to install 1.02 patch. I chose ok and it updated the game. BUT after the upgrade here is the error message I'm getting whenever I want to launch;

I think it downloaded the whole game but I don't know how .
