Hi. I am also having the exact same problem. However, I was able to make about four calls when I first installed Furikup, and it worked. But after those four calls, it has never worked again. I get to the "SELECT CONNECTION" screen, I select a connection, then the screen "fades" out most of the way, and sits. After about 10 seconds, the PSP shuts down, just like yours. If you find a solution, please post it here.

Thanks much!
