Quicksilver is being a pain for me to setup.

I want the Apple-space shortcut to work for Quicksilver. It sort of works through the Quicksilver Trigger by editing it from control-space to apple-space, however... it loads the thing in text mode so when I start typing it isn't searching for applications. I have to hit Escape to take it out of text mode and into application search mode!!!!!

I've set up a quicksilver shortcut using this guide:

Using that guide - its absolutely useless.. it will launch Quicksilver but that just puts the icon on the bottom bar.. it won't actually open the textbox where I can search for an app and load it.

So what gives?! Any help would be appreciated! Thanks
