I've gladly used Installer.app (3.0b4, 3.0b5). But last couple of days, the "refreshing resources" takes forever (~5 min) and then I can use Installer.app. However, none of the mentioned Tweaks for 1.1.1 (TIF exploit fix) etc. is available. What can I do to fix this, how do I re-install Installer.app? What files do I need to remove etc.?
