IntelliJ 8.1.4 won't start

Hello Markus,

I just installed Intellij 8.1.4, but it won't start. It displays the
splash screen, but nothing else happens. Where do I look for error
logs?

%USERHOME%/.IntelliJIdea8x/system/log on Windows, ~/Library/Caches/IntelliJIdea8x/log
on Mac

all plugins were working before i downloaded the update, so i will move all plugins and reinstall

OK a quick removal of all plugins fixed the bootup , but can't understand why they were working before the upgrade
