Plese Help

[Netheria]

I've downloaded everything the JPCSP thing said I needed and its still giving me errors, it wont run any of the games, I get them to load but I just sit on a black screen and when I push the "run" botton, it closes out. Im not a very techy person, but my husband is, he works on computers for a living, but he cant figure it out either.... I just really want to play loco roco and little big planet and Im to cheap to buy an actual psp, mostly because my son would destroy it...... Can someone please help us fix it and make it work? Id greatly appreciate it.

Thanks!
Yours, Netheria
