because the "cell" processer cant handle the awesomeness that is called Left 4 Dead.blitzkid1

So... Too Human is a rip-off of a game that hasn't even been announced yet?-Jiggles-

It prob has nothing to do with your OS.

Try fiddling with your graphic drivers and such.

If you have an updated PSP some themes will not work on it.

You have to add some crazy battery hack and downgrade your PSP for them to work.

anything with just a .ptf file goes into the PSP>THEME folder (you might have to make the folder).

Because their servers might be down or running slow? Wait a little and it will work.

Go find another site, they are all the same and will give you basically the same results.
