PS1 games on psp: The game could not be started. (80000004). Help

i downloaded crash team racing ontop my psp with the sony network downloader, but when i tried to boot it up on my psp it said: The game could not be started (80000004). I have the latest firmware.

Any ideas?

i downloaded the sony network downloader. i then bought CTR and opened it with the sony network downloader. my psp was pluggd in the whole time on usb mode. once the game had finished downloading i tried to boot it up but it gave me the message: the game could not be started 80000004.

the first time i did it wrong and didnt have the ony netwrok downloader, but i deleted the file and started again with the downloader.
