Update your firmware. Gen D2 is outdated. There is Gen D3, and the new Prometheus (basically D3 with a built in patcher for those newer games, I think.)www.pspslimhacks.com

ok i updated to gen d3 and it still dont work

Try updating to Prometheus, or patch the games using the utilities on that site for patching new games.

Not sure if it might help but from past experiences you may want to try to disable the Game plugin from the recovery menu of the PSP.Advanced>Advanced Configuration> Change "GAME plugins" to (Currently: Disabled)
This method is usually used for the Demo games.

did that still no go

If you have 2000 or 1000, you can update your psp to 6.30 ofw, play the demo and revert back to cfw later.
