help on homebrew game

i just recently paid someone to install CFW 3.71m33-2 on my PSP fat and upgrade it myself to m33-4. now the thing is, i downloaded a game, specifically, Silent Hill Origins to my psp. i was hoping to play it. the funny thing is whenever i run the game, it will like a normal UMD but i'll get a blank screen after the PSP thingy loaded. is there something wrong here?

Hm.. not sure, usually that would mean you need to update your psp to a higher firmware to be able to play the game, but i'm not sure.

try downloading another one, you might have gotton a broken game file or something.
And i guess it wouldnt be loadable if you didnt put it in the right folder, so i guess thats not it...
