Stupid Problem with my PS3

I bought Killzone 3 - used one Hardened edition

But the problem is when I insert this game the PS3 doesn't read the disc in like 20 sec the games come out and gets back in and after that also my PS3 doesn't read this game

any idea ?

P.S : All other games are working perfectly except this game.

Strange thing today I registered 2 PSN accounts and still counting

and dont use browser to register

make a new user go to sign up for PSN and create a new account follow those steps
