Display Exception from the Emulator

[harutonari]

Here I got an exception "your display format is not compatible with Jpcsp or the anti-aliasing settings is not supported by your display" from the emulator but I've just updated my display driver to the latest release version. I'm using a laptop(ASUS K42JZ) with intel i3-380M and AMD Mobility HD6470M in it. Besides updating my display driver, I've tried to adjust my screen's color depth to 32bit, closed the AA function, and started the emulator with the parameter followed: "%JAVA_HOME%\bin\java" -Xmx512m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=104m -Djava.library.path=lib/windows-x86 -jar bin/jpcsp.jar %*, but all doesn't work. I would appreciate if anyone could tell me possible solutions.
By the way, the beta number of emulator is 2611. I have also tried another earlier beta version, but the exception remains.
