(adsbygoogle = window.adsbygoogle || []).push({}); I made an account on my PS3 after installing rebug 3.55.1, it was the same username I use in the regular PSN but now that I try to log back in, it says email or password don't match or something like that.

It could be that I switched between SP-INT and PROD-QA. But then I made another user and used Quick sign up to play Killzone 3 online on the dev PSN but I can't connect to multiplayer. Is it that Killzone 3 only works using the Server Mapper to connect to regular PSN?

yep u changed the np-enivronment. change it back to the environment u used to create ur certain account then it should work, hope i helped

I created it under PROD-QA, that means I'll never be able to play online?

make another account on sp-int, then whenever u want to play online change to sp-int and whenever u want the free stuff change to prod-qa just like me

cheers
