App Home not installing apps

I'm trying to install apps from the Airspace store on my mac, but a few seconds after it starts to load (the bar doesn't move), it stops, and when I hover over the app it says 'Click to install'. I checked the log, and there's a bunch of error 401s. Also, I tried deleting the install directory and reinstalling everything, but I still have the same problem.

Please help.

UPDATE: I fixed the problem by logging out and logging back in (there must've been a plist file that didn't get deleted when I reinstalled it)
