Ngpsp Help!

Okay, so I downloaded the 1.5 version of NGPSP for my 1.5 psp. When i click on the ngpsp icon, it loads fine, and the menu screen appears. I click on load rom and nothing happens. I have placed sonic pocket adventure with a .ngp in the roms folder and when that didnt work i put it in the NGPSP folder and neither have been working. What's wrong?

is no one gonna help me? its been up for a while now and i know that many of you have NGPSP running and yet you refuse to help me out! Not very nice

Could be a bad dump of the game, Try another...
