Quicksilver weird problems

Everything is normal when I open an app from the dock. But when I try to open an app from Quicksilver different things happen:

-If I try to open a window from an app that's already open, one of two things happen: when I open Safari from /Previous Systems.localized/2005-05-03_1044/Applications/Safari.app (line from bottom of Quicksilver "window"), it will give me a window if hidden or bring up a window that's open like it should. When I open Safari from /Applications/Safari.app, a new Safari icon pops up on the right in the dock and a whole new application opens even though Safari was already open. This happens with applications such as Mail, iChat, and Safari.

-Almost all apps have two options like above, but some (iPhoto, iMovie) have the correct icon for only the application from /Applications/iMovie HD.app. When I use that one, everything is normal. The app from /Previous Systems.localized/2005-05-03_1044/Applications/iMovieHD.app has a faded icon that has a ruler, pencil, and paint brush with a "Do Not Enter" sign above it. If I try to open that, nothing will happen. This is what happens with most applications, such as all iLife applications, Tube TV, and Handbrake.

-Some apps will have just one option and will do everything normal when selected. These apps are from /Applications/Audio Hijack Pro.app or something like that, such as /Applications/iWork '08/Pages.app. None of these apps that only have one option have the /Previous Systems.localized/2005-05-03_1044/Applications/. These are apps such as Audio Hijack Pro, iWork apps, MS Office apps, and Onyx.

In conclusion, it sounds to me like most apps work from /Applications/... and some only have one option from that location. Others have two locations and it only works from /Previous Systems.localized/... and others have two options that have the /Previous Systems.localized/ icon faded. I though there were two locations of these apps, but I could only find one. When I did a spotlight search of Safari, I could only find the one from /Applications. All these apps that I mentioned are in my dock. It's annoying when a whole new Safari app opens. Anyone have any advice? ANY deas would be helpful. Thanks in advanced and sorry for the long post!

 

Does anyone have any idea what I'm talking about? I also saw this "two locations" thing when I was using OmniDiskSweeper, but I still can't find the Previous Systems thing ANYWHERE! It's driving me bonkers!

 

Ok. I found the previous systems folder after searching everywhere. It's on the Macintosh HD device, so I click on that and I can see lots of choices. Previous Systems is on there. It has all my applications on there as well as other stuff. Can I delete that entire folder or will that make my computer crash? I'm hoping I can save some space on my HD by doing this. Should I or shouldn't I??

 

Ok I figured it out. I just dragged the apps from the Applications folder on the Dock. Quicksilver is working better now. Does anyone know of a way to set Quicksilver to not look in the Previous Systems folder?
