App Store on MBP Won't Update ANY apps.

I've had three apps, and 1 system update sitting in my Mac App store since yesterday, yet, whenever I go to click 'Update all', or try and update apps individually, I get a 'Checking for updates' wheel, and can't do anything else within the App store. The top navigation buttons go grey, I can search but don't get any results, and I'm at a loss as to how to fix this.


Any ideas?

Macbook, Mac OS X (10.5.7)

This procedure will delete certain temporary and cache files used by system processes. The files are automatically generated and don't contain any of your data. Occasionally they can become corrupt and cause problems such as yours.

Back up all data before proceeding.

Triple-click anywhere in the line below on this page to select it:

/var/folders/zz

Right-click or control-click the highlighted line and select

Services Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with a subfolder named "zz" selected. Move that subfolder to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
