FW 3.10 OE-A2 and official demos?

I tried searching to see if there are any issues with this firmware and the official demos, but didn't see anything in the forum. I've downloaded both Killzone and Syphon Filter demos, and placed them in my "PSP/GAME" directory - and my PSP recognizes them off the memory stick, but when I try to load either one, the PSP just powers down anyone else run into this problem?

Thanks...

place all official demos in the game310 folder that should fix it or go into recovery and change the game folder to 3.10 kernel mode.

no dont put your demos in the GAME310 folder they dont work keep them in the GAME folder then go in to recovery and set the kernal to 3.10
