I've installed the new alpha of Quicksilver, (after clearing out all my cache/preferences).
But after configuring it at the start, I can't invoke the program. It doesn't show in the dock, no menu bar item, default or set hotkeys don't work. If I have the application in my dock and run it, it doesn't even show it as running when it's launched. It's there in Activity Monitor, so something's happening, but no idea.
