Problem with Ratchet infrastructure

I have a Ratchet and Clank:SM full .cso on my memo stick and when i try to play
on infrastructure it says<loading multiplayer data failed> then i select infrastructure,then the screen goes dim and nothing happens.Ive searched for help but every one says that the wifi is screwed up, but i can play other games
on infrastructure and there is no problem. thank you for any help

B/W: Ive tried it with and without a umd in the drive.The umd is MLB06

People have had problems with this game on custom firmware.

Try changing some settings in the recovery menu so that the PSP boots into the 3.40 kernel also enable "No-UMD" and setting the CPU to 266mhz.

Im not entirely sure if these settings will work. If they dont work then try them again but with "No-UMD" disabled.
