Can't run Jpcsp

[Karabalka]

I tried to use Jpcsp 0.6 2324 on my desktop computer and netbook. I have Windows XP SP3 and Java 6 update 27 installed on both machines. On desktop computer running start-windows-x86.bat shows console window with "Running Jpcsp 32bit..." message, then shows the GUI for half a second and exits. What could it be? On netbook GUI starts normal but when I choose "Load UMD" from the menu, no dialog appears and there are some messages in console:

Code:
