JPCSP won't run games

[wildwind1290]

About two months ago I got my hands on JPCSP and a copy of SD Gundam G Generation Overworld. It took a bit of wangling, but I was able to get the game to run eventually. I don't know what I did with it, though, because it somehow vanished off my desktop when I wanted to get back to playing it.

So I redownloaded another set and now it absolutely refuses to work. I'm running the 64 bit on 64 bit Windows 7 with Java Update 7 version 21 for 64 bit. The emulator's an older build, but it's the same one I downloaded originally. It starts up alright, but when I load it and hit Run, I get nothing. The game sits at a black screen until I shut it down and it never works.

Help, please? This thing was working fine two months ago.

works fine for me using the latest 64 bit version (r3148)
get the latest build from here

[serio]

if it still doesn't run, post a log. descriptions are useless, they don't tell the devs anything about the problem since more often than not they don't have the game and/or never even heard of it.

Got the latest version, still having problems.

Here's the log, seeing as you asked.
