"Cannot copy EBOOT, Cannot find the specified file
Make sure you specify thee correct path and name"

help!

this is what happens with the second socom demo too

I had a problem with a corupted file. Deleted, downloaded and put on psp, then it worked.

Go to pspdemocenter.com on your psp browser and just directly download.. works every time.

I think that can also be downloaded from....www.sony.com/psp... when you go to downloads and then game downloads, when you are downloading it, make sure that you dont do anything else while its downloading, like minumize it and go browse another site or anything, just wait till its finished downloading, and then make sure its not a fold with in a folder make sure its something like

USLS1463967900/EBOOT

Then right click go to new , then just open your psp memorstick and the psp root folder, then drag and drop it to GAME
