Xcode installation seems corrupt? I've been try to download Xcode for work, but for some reason the Mac App Store is giving me a bit of trouble. Activity monitor shows some network usage, but in Launchpad it seems the download isn't moving. 

When I go to the purchases panel of the Mac App Store, I see this. 



No status, no pause button, in fact - the button has no text on it! I've tried restarting the App Store, restarting my computer, even removing the com.apple.appstore folder in /var/folders but alas, no luck.

Can anyone diagnose the issue? When I removed com.apple.appstore, Xcode still showed up on Launchpad, and clicking on it did nothing - it was frozen in time. So can I kill off this partial download and start new?
As near as I can tell, this might be a Hidden Purchase. Choose Store > View My Account, where you can see hidden purchases. You may be able to cancel or unhide the download from there.
