I thought something was up when every PSPAdvance thread closed. How are we supposed to talk about the program if we have no place to?
Why, Why did I install this program. I have had the most stable system up until now. I get a BSOD when I open the advanced media player on my PC. I run the program on my psp and it just hangs at choose an mp3 then powers off after 20 secs. Nice try guys, maybe next time.
