every time i open installer.app and i try to install something, the installer downloads the package, but then it doesn't install anything and it just shuts down. this started to happen today.. in the past days i installed a lot of stuff.. i thought it was a space issue, so i tried uninstalling a few apps to free space, but the problem is still there. how to fix it? i can't install anything but iphysics levelpacks and other addons (i think because they don't add any new icon to the board!) help! and thanks in advance.
